I have had to cull 4 hens! This hen started with the same vent problem today and I know it will just get worse despite my efforts. I am kind of new to this. I inherited these chickens and not really good about identifying breeds( so if you can tell me breed too would be great). From my research I think it starts with vent gleet then turns into a prolapse? I try everything...apple cider vinegar in water, yogurt, pro biotics, cleaning them up with Epsom salt baths then treating with neosporin and hemorrhoid cream. I even have done the blue coat. It just gets worse, they quit laying and I feel like they are suffering and it's over. So today I am fed up and SAD!! I took I hope good pictures so any input would be helpful. Just some other random info I feel like I keep coop clean, pellet diet and scratch in evening and table scraps as well as what I mentioned, We do have two male ducks that I feel like in the last 6 months have gotten aggressive with the hens for whatever reason and try to mate with them. I am wondering if this could be the problem? I just separated ducks today. No other chickens or rooster picking on her. Currently this hen is in a box in the barn hoping she will rest and not lay. I hope I have caught it soon enough and she gets better. This is what she looks like This is looking at top of her back feathers. When the vent stuff starts happening with my hens it seems their feather in back start looking "fuzzy" Here is the vent. Notice some of discharge. This is right after she laid a nice normal size brown egg...with blood all over shell. Thanks for any input!!
