I have saveral 15 week old batam chicks, 2 of which are roo's for sure maybe a third its a silkie so dont know. I don't know who is making the noise, they stop when i go outside. Early in the morning for the last few mornings I have heard one of them making a squawking/choking (lack of better word) sound. Kind of really sounds like it is choking or strangling....Could this be an atempt at crowing this early? Or is something more serious going on?
