Hello, We, my partner David and I, are new to BYC. Hello! The main reason we've signed up is we recently bought new chickens and a chicken tractor/coop. Two chickens are pullets, two are adults, about 1 year old. Chickens aren't new to us, but these chickens are. Our issue - the adults are an Aracana and a black Sex-link. When they first joined us, they both gave us eggs for a few days. Now, for about a week, only the Aracana is laying. The Black Sex-link seems happy and healthy but hasn't laid at all in that time. We don't understand. Any help is very much welcomed!
