I know this thread was from earlier in the month, but this was very helpful to reassure me while I'm treating a vent-pecked hen. She is/was the bottom of the pecking order and, unfortunately, got pecked during laying on Thursday, resulting in prolapse. We were able to get antibiotics and anti-inflammatories from the vet, but did not feel comfortable going through with purse string sutures and hormone implants (especially since the price was way more than we could currently afford). We have since been treating her at home separate from the flock.
I was seeing the scab in her vent whenever she needed to poop and at first thought it was poop stuck to her, and I tried another epsom salt soak for her. Now I know it's a scab and to just continue her care as I've been doing (daily ointment, moisturizing, antibiotics and anti-inflammatory, daily calcium citrate, checking her vent to make sure everything is staying in -- and it has since Thursday night). It's been quite stressful, I've been micro-analyzing everything, and now I'm hopeful she will make it through all right. Been feeding her extra treats/yogurt/etc because she is uncomfortable and lonely without the rest of her flock, but I want to make sure she is able to poop without extra effort or visible discomfort before I allow her to reintegrate.
Thanks for posting pics, it was a great comparison to what I was seeing.
