Andalusian Chickens: Blue Mediterranean Breed Guide
A complete guide to Blue Andalusian chickens: 150-200 white eggs a year, active heat-tolerant temperament, slate-blue laced looks, blue genetics, size, and care.
The Blue Andalusian is one of the most elegant chickens in the backyard world, a Mediterranean breed cloaked in slate-blue feathers each laced with a darker edge. Beyond the looks, it is a productive white-egg layer that handles heat beautifully, making it a smart alternative to the Leghorn in hot climates. Active, alert, and striking, the Andalusian suits keepers who want a beautiful, efficient bird and have the space to let it range.

Egg production and egg color
Andalusians lay about 150 to 200 white eggs a year, and good production lines can do better. Reflecting their Mediterranean heritage, pullets often start a little early, around 20 to 24 weeks, and they lay steadily through warm weather, with the usual dip in deep winter and during molt. They are an efficient layer with a lean, low-feed-cost frame.
The eggs are white, medium to large, and chalky in the classic Mediterranean style. For keepers in hot regions who want white eggs without the Leghorn's flighty extremes, the Andalusian is a productive, more colorful option. Feed a complete 16 percent layer ration with free-choice oyster shell to keep those white shells strong.
The blue color and its genetics
The Andalusian's signature blue is worth understanding before you breed them. Blue plumage comes from a single dose of the blue gene, which does not breed true. Mate two blue birds and the chicks fall out roughly one quarter black, one half blue, and one quarter splash, the pale gray-and-white pattern. So a breeding flock naturally yields all three colors, and only the blue birds show the classic slate-laced look. This is normal genetics rather than a flaw, and many keepers enjoy the variety of colors it produces in each hatch.
Temperament and personality
Andalusians are active, alert, and somewhat flighty, very much in the Mediterranean mold. They are not aggressive, but they are independent, busy birds that would rather forage than be handled, and they can be good fliers. Raised with consistent gentle contact from a young age, they become reasonably tame, but they are never going to be cuddly lap chickens. They suit keepers who appreciate an energetic, striking bird and can give them room and a tall or covered run.
Cold and heat hardiness
Heat tolerance is the Andalusian's strong suit. Their lean bodies, large single comb, and active habits all help them shed heat, so they handle hot summers far better than heavy, fluffy breeds, which is a major reason to keep them in warm climates. The trade-off comes in winter: the large comb is prone to frostbite in hard freezes. In cold regions, keep housing dry and draft-free with good ventilation, and consider a protective balm on combs during deep cold snaps.
Size and appearance
Andalusians are a light to medium breed. Hens weigh about 5 pounds and roosters about 7 pounds, with a slim, upright, refined carriage. The classic blue bird is a soft slate-blue with each feather neatly laced in darker blue-black, a look that is genuinely eye-catching in the yard. They have a large single comb, white earlobes, and slate legs. They are kept for white eggs and beauty rather than meat. Allow roughly 4 square feet of coop floor per bird plus a generous, ideally covered, run since they fly well.

Broodiness and raising chicks
Andalusians rarely go broody, in keeping with their Mediterranean genetics that favor laying over sitting. That keeps the white eggs coming but means you will usually need an incubator, or a broody hen of another breed, to hatch them. When you do hatch a clutch, remember the blue genetics: expect a mix of black, blue, and splash chicks. The chicks are active and quick to feather, growing into the lean, energetic birds the breed is known for.
Everyday care
Care is simple. Provide a complete layer feed at point of lay, constant fresh, cool water, insoluble grit for foragers, and free-choice oyster shell. Offer one nesting box per three to four hens, dry roosts off the floor, and predator-proof housing, ideally with a tall or covered run since Andalusians fly well. In winter watch the large comb for frostbite; in summer make the most of their natural heat tolerance with shade and plenty of water. Keep bedding dry and watch for mites and lice.

Is the Andalusian right for you?
Choose an Andalusian if you want a strikingly beautiful, heat-tolerant white-egg layer and you enjoy an active, independent bird. It is an excellent pick for hot climates and for keepers who appreciate the variety the blue genetics bring to each hatch. If you want a calm lap chicken or a cold-climate winter layer, a heavier, smaller-combed breed may suit you better, but for elegance and warm-weather productivity, the Andalusian is a standout.
Frequently Asked Questions
How many eggs do Andalusians lay per year?
Blue Andalusians are good layers, producing roughly 150 to 200 white eggs a year, and well-bred lines can reach higher. Pullets often start a little early, around 20 to 24 weeks, reflecting their Mediterranean, Leghorn-adjacent heritage. As an active, lean breed they lay steadily through warm weather and tolerate heat well, with the usual slowdown during deep winter and the annual molt.
What color eggs do Andalusians lay?
Andalusians lay white eggs, typically medium to large and chalky white, in keeping with their Mediterranean class. They are a productive white-egg layer for a heat-tolerant breed, which makes them a useful alternative to the Leghorn in hot climates. Feeding a complete layer ration with free-choice oyster shell keeps the white shells strong and the supply consistent.
Why are Blue Andalusians not always blue?
The blue color in Andalusians comes from a single dose of the blue gene, which does not breed true. When you cross two blue birds, the chicks come out roughly one quarter black, one half blue, and one quarter splash, a pale white-and-gray pattern. So a flock of breeding Andalusians naturally produces black, blue, and splash birds, and only the blue ones show the classic slate-laced look. This is normal genetics, not a fault.
Are Andalusians friendly?
Andalusians are active, alert, and somewhat flighty rather than cuddly, much like other Mediterranean breeds. They are not aggressive, and they can become reasonably tame with consistent gentle handling from a young age, but they are independent birds that prefer to keep busy foraging over sitting in your lap. They suit keepers who appreciate a striking, energetic bird and have space for them to range.
Are Andalusians heat tolerant?
Very. Andalusians are a Mediterranean breed built for warm climates: lean bodies, a large single comb, and active habits all help them shed heat, so they handle hot summers far better than heavy, fluffy breeds. The flip side is that the large comb is prone to frostbite in hard winters, so in cold regions keep housing dry and draft-free, provide good ventilation, and consider a barrier balm on combs during deep freezes.
Do Andalusians go broody?
Andalusians rarely go broody. Like most Mediterranean breeds they favor steady laying over sitting, so they seldom stop to brood, which keeps the white eggs coming. If you want to hatch Andalusian chicks, plan on an incubator or a broody hen of another breed. The upside of the low broody instinct is reliable, season-long egg production.
How big do Andalusians get?
Andalusians are a light to medium breed. Hens weigh about 5 pounds and roosters about 7 pounds, with a slim, upright, elegant carriage. They are kept mainly for white eggs and their striking looks rather than meat. Their lean build and active foraging make them efficient, economical birds. Plan on about 4 square feet of coop floor per bird plus a generous run, and note they are good fliers that benefit from a covered or tall run.
