I've got 2 chickens, 1 of them I introduced later after giving away my other chicken (swapped a large australorp for a bantam). it's bigger then my other chicken but is lower on the pecking order. the original australorp and my other chicken used to get on great but I swapped it because it was noisy and also a bit too large for my yard. however the new bantam australorp has always been bullied by the other chicken. it was never happy sharing the coop with it. however for a while they did but it never let it roost next to it. the other chicken has been broody for months and it won't let the australorp in. or if it does let it in it sits on the ground because it won't let it on the roost or even on the hay part. everynight the australorp roosts on top of the coop. what can I do?
