They are about 5 to 6 months old the last batch I got were just starting to lay, you put your name on the list and when they get about 75 birds they order them. I've never got a sick bird only great hens so far the only thing is they have been debeaked which I don't like and they don't know to run or fly off but they learn pretty quick!Do you know the age on them? I've got to pick up feed Friday from the coop.
