I am a first time chicken mom. I have 3 babies, 5 days old. One is dealing with pasty butt, I cleaned her once earlier today and then had to clean her again tonight. I applied some olive oil. Now her but is red and exposed due to the oil, when I put her back in the brooder she was chirping constantly and walking around funny. I took her out and have been holding her for about an hour. She's sleeping and calm. I am worried about putting her back with the other 2 that they may peck at her? Any suggestions?
