I picked up 3 Salmon Faverolle chicks today at my local feed store that were some of the only survivors of a weak shipment of chicks they received last week. Two of the 3 are doing great, the last one had a pasty butt and when I went to clean it I discovered I was wiping away blood too it has what appears to be almost a cut about a half inch in length right below it's vent. I cleaned her up and put neosporin on the cut, but she is noticeably weaker then the others. I also have given them added electrolytes in the water. Any other suggestions?
