I have an old Pekin hen who absolutely loves me. She has seen her mate get killed and her other hen killed the year before. She really isnt growing her wings back. Her 3rd wing seems is only her blood wings. She had a sinus infection for a long time until I figured out that problem and started giving her VetX every night. I think she loves it plus the attention. I also began to put vitamins in their water. She is spry and happy. The problem is that she will preen but she wont get into the pool unless I just filled it. She is filthy gray and looks horrible. I took her out and put the others in their houses. I then proceded to put her in, let her preen but it wasnt much. I then physically washed her in the pool to no avail. I then used a towel to wash her. She looks a bit better but still very gray and dirty. Can I used Dawn dish soap to wash her in separate buckets of course to clean her and get her white back? She is a silly cute hen who hangs around me all the time. I swear she knows what I am saying to her. I would just like to help her become normal white again.
