Hi everyone, new here and I have a question. We have 6 hens all together but for awhile now, 4 of the Welsummers have been going after our Wyondotte mostly around her head. I have been looking at her and I have not noticed anything wrong (mites, infections etc...) Now for the past 2-3 days, these same Welsummers have been going after their Welsummer sister to the point that I thought she was molting, until I saw and heard it tonight. This is our first time ever having chickens and we don't know what to do. They do not free range (do to neighbor). Should we separate the two being attacked and keep those 2 together? Any suggestions will be greatly appreciated.
