ISA Brown Chickens
ISA Brown Chickens are named for the Institute de Selection Animale, who originally came up with the cross-breed in the 1970s. One of the leading breeds for commercial brown egg production, ISAs will lay prolifically their first 18 months, sometimes longer. If you’re looking for the number one brown egg producer for a laying flock, this is the one.
These ISA Brown Chickens were originally created like other Gold and Red Sex Links using Rhode Island White Female and the Rhode Island Red Male. The result is a hardy and robust dual purpose breed with superior egg laying capabilities as well as substantial size for meat.
While our ISA Browns are very similar to the original sex links, there are many other undisclosed genetics. Complete genetics are withheld for the purpose of protecting our breeders and hatchery.
Why They are One of the Most Popular Chicken Breeds
ISA Brown Chicks are one of the most prolific egg laying chicks that we offer. They are a slightly smaller breed. Hens weigh approximately 4.25 pounds, and have an excellent feed to lay conversion ratio. These will best just about any other egg layer on the market and are ideal for larger laying flocks.
The hatchery can easily determine the gender of these chicks:
Male ISA Brown Chicks will be completely white.
Female ISA Brown Chicks will be reddish buff or gold with streaks of white.
