I have this buff Orpington hen who has an issue with her vent area. It was noticed just today and was not like this two days ago. We saw another hen pecking at her and separated her immediately. Looking closer it looks like the skin right below her vent is split about 2.5 inches wide. We sprayed with vetericyn right away to sterilize and promote some sort of healing. Then we checked my other 12 hens and found three others with slightly the same problem. It is not as bad yet on them. One is slightly through and the others just have some scab skin there. The hens are all 7-8 months old and very healthy. Fed completely organic. They have plenty of roost space and there is nothing sharp to cause the cut. Can someone please give me some information. If there is anything? We have no local vets and non that will take care of chickens anywhere within 2 hours. Thanks.
