I have 5 bantams and a regular large hybrid hen, we recently rescued a chicken from a friend, it had become stuck in a fence, was injured and the others had badly attacked it and it would not reintegrate. At first all was fine, but we soon realised it was actually a young cockerel. Whilst we tried to make alternative arrangements for him we noticed he was interested in the hybrid large hen (No probs there) and the only one of our bantams that is laying ( the rest are too young at the moment), unfortunately the bantam that's in lay is a bit lame ( she was also a rescue, and is 'wonky' on one side) she tried frantically to avoid him but he was chasing her round all the time. He made a swift exist from the flock after we realised this and she was in quite a bad way. He has been gone a couple of days now but she will still stay in the coop nest box, she isnt preening, and has stopped laying but when we make her come out of the coop she will eat and drink. The others are also giving her a hard time as well now and she is back to limping on one side with her lame leg, whereas this had practically gone before and she was strong and sturdy. We have considered moving into an isolation cage and keeping her warm and away from the others for a while but worried that the shock of going back to the cold and in with the others will be just as bad, also concerned that the pecking order has been messed with quite allot recently and disrupting it again may only prolong the bad times.
Desperately want for our happy healthy flock to get back on track again.
Any tips or advice?
