I've had a bantam rooster for about a week now in a separate pen and I mixed him in with my flock of girls today for the first time when they were free ranging. Everything was going great, he immediately took over and he was the boss. That is, until he met Bertha. Bertha is HUGE and is my dominant hen. She definitely won the fight that lasted maybe 15 seconds... He's got some battle wounds in his comb and his ego is busted, but I'm not concerned about that. My concern is, will they ever get along? When and if should I try again? This is Bertha and nobody messes with her.
