Okay so I think I did a VERY bad thing?!? I cleaned out the coop, put fresh bedding down and DH rearranged the roosts & nesting boxes to make cleaning easier in the future. Since the chickens (aside from Broody momma hen who didn't leave during the cleaning process...so her nesting box is still dirty) have been reintroduced to their updated home, I have had a problem. For the past 2 hours now, Alpha rooster, Jeremy, has been doing nothing but chasing and attacking the other rooster, Timmy. I thought with all the commotion that a predator had snuck in and went out to find Timmy hiding in the nesting box with momma broody (who was growling and making her protest known). I go to leave when Jeremy "drags" Timmy out and chases him around the coop, into the run and corners him. Timmy NEVER fights back, but just runs away and tries to hide.
Aside from culling one of them, is there anything I can do? Is this sudden aggression because of the rearrangement? Could the weather be causing his aggression or the fact that we have a broody? He is completely fine with the ladies and is sweet to me (I don't handle him though, so by sweet, I mean he follows me around enough to see if I have any treats for him and then leaves me alone if I don't. He also ignores DD, so that makes me happy). Do you have any suggestions/ideas/anything? Thank you in advanced!!
