I have a young mixed flock of ameruacana and barred rock. Bought as chicks I think we have several Roos and had planned on rehoming the amerucana since he wasn't as social as the other Roos. However today I introduced 4 silkies who were met with tolerance by most. Our head roo was a little aggressive but settled down. But the antisocial boy seems to love the new group. Hung with them all day and never attempted to peck at anyone. I have the silkies still separated at night to assure they're safety and when I went to check on everyone the roo was laying down alongside the fence to be close to the new girls. Do Roos claim certain groups to them selves? Will he help defend his girls? I am reconsidering letting him stay after he seems to have bonded with the silkies now.
