Hello, I am going to try and list her info as best as I can. Vern is 1yr old. She went Broody this spring and hatched 3 chicks. She was free ranging in the back yard, and was attacked by a fox. One chick died, and I thought I had lost Vern too. About 5 hrs later she had dragged herself back to her coop. There was a trail of blood up the bank to the coop from where she had been hiding. There was also "gore" from her vent area. I was worried it was her insides , but with my husbands help we washed her rear with warm water and light soap. I saw no open wouds. I checked her the next day, and saw what appeared to be bruising. She still had the chicks still, but was clearly in pain. I kept her seperate during the first few days, and I put her with them at night. This arrangement seemed to work, and over the coarse of 1-2 weeks she accepted the babies more, and more. She seemed to be healing/healed. Normal behavior resumed. This is the only trauma I know she has experienced. It happened about 4 weeks ago. Yesterday she started roosting with the babies. They are well over 6 weeks old now so I just figured it was that time. When she was exiting the coop yesterday a rooster jumped off the roost and landed on her, but it seemed like normal chicken morning chaos. I have been waging war on mites. I washed chicken butts 2 days ago for mites, but just sprayed Vern because I didnt want to stress her and the babies. I am trying Spinosad after not enough luck with neem. This morning I noticed she had "sad chicken tail".she was eatting, and participating with the flock so I thought I would keep an eye on her. When I got back to the house today, and went to close up the chooks I noticed she was panting, and still had sad chicken tail.. No other chicken is behaving the same. I also checked all other butts, and no one else's looks like hers. I have attached a pic below. I took it right before this post. I don't want to put her through a vet visit if it isn't nessicary. I also don't want to put her down if I don't need to. I'm not sure if I missed anything, but please help me if you can. She clearly still has bugs. Everyone who got a butt wash has improved a lot. Maybe a warm bath would help her? The abscesses are warm and feel "full" she tolerated me looking at her bum, but she didnt love it. The one on the bottom is ping pong ball sized. I'm so worried about her. I also posted a pic of her roosting on the edge of her brood box last night. For comparison. Since tackling these mites I switched the bedding from wood chips to forest debris. Pine needles and dried leaves. I have sprinkled wood ash, and putting mint and geranium in the bedding and nest areas. I do not think/have not noticed her laying an egg yet since she went brood in April. I hope I covered my bases. I'm looking anxiously for replys. Sorry for the essay, but I'm sure the more info the better right?
