My mom has a completely enclosed coop, nothing can get in and nothing gets out. She has 6 chickens. 2 Speckled Sussex, 2 Ideal 236, 1 Polish and 1 Golden Penciled Hamburg. Two very strange things started happening lately: 1) Someone is crowing. But all of the birds are over 8 months old. Shouldn't this rooster started crowing sooner? if its a rooster? 2) Someone is laying a blue tinted egg. There are no Americauna on this pen or even in this neighborhood. We get white eggs from the 236's, we get light brown specked eggs from the Sussex. There is a cream colored egg and a blue. I have Polish and get teardrop cream eggs from them. Could it be that the Hamburg is laying this blue egg? and if so, who is crowing? We are utterly perplexed. Help.
