This is one of my pullets that has not been feeling well and today I noticed she had matting around her vent so I gave her bath. Then I noticed this of her vent and panicked!! First after the bath I gave her an epsom salt soak with some electrolytes and now I'm going to try some yogurt (if I have any left). She could be laying by now, but not really sure. After I gave her the salt bath I noticed she still had all this around her vent. So, I soaked a rag with warm water at lightly pressed on her vent. It seems to be slow coming off, but I really need so help on this one. I'm going to continue with the warm compress because it seems to be working getting this stuff off. It also looks like liquid is oozing out after I use the warm compression. I'm so scared because I don't know how long she has been like this. We have had triple digits for the past 2 weeks with heat index and it's been so hard to keep my babies cool and myself. I feel like I let her down not noticing this sooner. Thank you for any help!!
