I have two 2 year old black sex links who are both freeloaders right now due to molting and four 18 week old pullets. Three of the pullets have gotten super loud, my two Australorps and my RIR. The australorps are also squatting for me. I attached a picture of one Australorp and my RIR...are they looking mature around the comb? Is all the sqwauking a sign eggs may be coming soon? Thanks!
