Please Help! I was given 2 hens 2 days ago, Barred Rock and Araucana.. I already had 7 chickens 4 are RI Reds and 3 are NH's.. The 2 Roosters are NH's.. As of today the rooster that was the calm one is not viciously attacking the other Roo since 2 hens were added in.. The Roo who is being attacked is now bleeding and his knob thing on his foot has been taken off... Why is this happening since the 2 new hens came? Is it a dominance thing? Will this stop or should I re-home the Roo that is taking a beating? Please help...
