I noticed my oldest and favorite Silkie Hen was looking smaller than normal 2 days ago and so I took her out of the coop and brought her inside in a brooder box to give her some extra special food for a couple of days. When I went to put her back in the coop today with my 3 Roos and 2 other hens, 2 of the Roosters jumped on her and were flogging her. They just kept going after her until I finally got her back out. I did this in the daylight, What should I do? Is this normal? Should I have waited for night and the red light only? I am pretty new at this so I am not sure how to deal with it.
