I think my chicks are about 7wks old now. We ordered all pullets... but obviously have one beautiful cockerel for sure! (he even crowed loudly for the first time this morning once we put them out in the run) The behaviors in question are.... we're not sure if there are more boys. We have a couple chicks (haven't crowed but sounds like they're trying) but they run and ram their chests into the roo... w/ their head feather's all spiked up. Are they just aggressive pullets? Or is that roo type behaviors? Also... I read that roo's have a claw or something like that on the back of their legs? When do they develop this? And If there's a bump there now.... does that mean it's a boy? Or do the girls have a bump there too, that just doesn't grow into a claw (or whatever it is)? I hope that rambling makes some sense to someone! TIA!
