You're right they are easy to tell pretty early. It of my 8 straight run l had six hens and two roosters. I got lucky. They are just beginning to lay now. Love the darker egg color. Much different than my Welsummer and marans.
Chickencanoe how old are the chicks where you can see the huge difference in their combs? I just got my first 8 Penedesencas straight run and am curious to see how many pullets vs. roosters I received.
