To my kids amazement and and my neighbors concern one of my barred rock hens starting crowing yesterday. We are excited to have chicks ( if the neighbors will put up with him) but I have no idea about breeding or hatching. There are 14 hens that are older (both RIR and BR) living with the new flock of what I believe are 6 hens (BR) and 4 roosters (BR). Only 1 rooster has started crowing but there are 3 others that are the same light feather color but do not have the developed comb as the big boy. My questions are, will they lay and hatch chicks naturaly( I mean around the other older hens)? Should I seperate the new flock from the old? Does it matter what time of year it is? I would appreciate any assistance anyone could give.
