This morning about 6 a.m. before the sun came up I believe opossum attacked my chickens in their coop they all came out and one of them is missing all their tail feathers and has a bloody behind. She's walking around fine. She won't let me catch her. The Coop door was accidentally left open last night.
You need to try to catch her so you can take a closer look. Call them over for treats, hopefully you can get her.I went and bought some vetericyn. But I can't even get her to let me spray her wound with it. Two of my chickens let me pick him up all the time and then the other two run. I think I may have to wait for her to go to roost this evening and grab her and put her in the house in a dog kennel. Any pointers on trying to catch her?
Since you have Vetericyn, that will be just fine. Flush the wound very well first, you can use soapy water, saline, hibiclens, betadine -whatever you have on hand. Dry her a bit, then apply your Vetericyn.
Take a good close look at the wound to determine how much damage there is - is it just the tail feathers ripped out or is her vent damaged too.
When you have time, more photos would be good.
Keep us posted.
