After hatching from eggs 4 months ago, we ended up with 3 cockerels and 1 pullet. I'm planning to rehome two of the cockerels and hope to get some chicks from the remaining pair. The pullet is a barred rock. for other other three I've got 1 barred rock, 1 buff brahma and 1 blue ameraucana. Any suggestions on which would make for the best pair? How long might it take for them to mate? thanks for the advice!!
