Breed originated in Australia developed from Black Orpingtons and was introduced to the U.S. in 1920's. Black Australorps are one of the most popular producers of large brown eggs and they are known for persistency of lay even in hot weather. One Black Australorp hen set a laying record of 364 eggs in 365 days. The green sheen of this solid black plumage bird presents a truly beautiful sight, particularly when the sun is reflecting off the plumage. Pullets mature early and many will be in production between 5 and 6 months of age. Chicks are black with a good deal of white in the underparts and small white patches around the head and wings. Black Australorps are quiet, gentle, and stand confinement well.
