I forgot to mention - I accidently got two roosters before and they crowed very early on. I have never heard this roo crow. I actually hear an egg song coming from him which is why I did not even think that she was a he.
Goodnight!
like dinare said they are slow to mature and he might of just been calling to tje hens. ironically i jave this buff brahma roo that makes rhese weird noises they kinda sound like an egg song but he is just calling to the hens. that could be what yours is doing
