My hen who is a year old Partridge Cochin was on the roosting bar this morning and didn't get down to eat when I came in. I went to check on her and noticed that she had blood on her rear end under her vent. It appeared to be a lot and I brought her in the house to check it out. I felt her gently and thought maybe she was egg bound. I got online to read about how to treat her and followed these instructions. First I tried to clean up the blood so I could get a good look and thought her rear end looked strange almost as though she has split her skin from the vent down. I cleaned her up a bit and there isn't any fresh bleeding. Next I got a glove and Vaseline so I could check to see if there was an egg I could feel. When I inserted my finger in about 2 inched straight in, She strained a bit and pooped, so no egg is there. Next, I tried to give her some calcium that was broke up. She pecked a little of it but not a lot. I made a warm bath in my sink and put her in it for 15 minutes. She almost went to sleep and enjoyed it. I made sure to dry her off with a towel and hair dryer. Upon looking at her rear, it does appear that she has split her skin so I placed some antibacterial (Blue Kote) on her and put her into my clothes basket with more calcium mixed with a little food and some water. She laid down and and has not moved since. She doesn't appear to be uncomfortable, but I am very concerned for her. Any Advice is GREATLY appreciated.
