I just got a trio of Bard Rock Banties. The little hens are docile and sweet but the roo--Look out! He started crowing the second his feet hit the ground and he flogs me anytime I open the door to his pen! He is very aggressive! If I catch him and hold him he wiggles around till he can bite my hand! He even flogs the side of the pen if I hold my hand up against it. Do I have any hope of reforming him or should I cut him loose and take my losses?
