In my case, i didnt have any rodents, rats, etc. Same as you. I had to assume it was fly strike. there has to be something present to lay the eggs in, so I also assumed there either had to be a small wound I didnt see for them to lay eggs in, or it was the little bit of poopy butt. either way we got them thank goodness.I applied Neosporin, but not to smother the maggots. I wanted the maggots alive, so I could easily extract them. I didn't want them dead under her skin, because her immune system would have to work double duty to clear them from her body. I checked for 3 consecutive days (taking into consideration the 8-20 hour egg hatching/life cycle) to ensure all were extracted. Then applied Neosporin to prevent infection and aid skin healing.
Yeah, I agree. Luckily, I had an experienced staffer at a local feed and farm supply provide excellent advice on product selection and ongoing treatment. She saved me a bunch of money, and gave sound, practical information about what was best for my situation.
I'm happy to report, she's doing great and continuing to heal. I still have her isolated from the other hens to prevent them from pecking at her healing wound. When the skin is completely closed, I'll re-introduce at nighttime.
I read the post about May May's condition and it sounds identical, in the same spot and everything. I still don't know what caused this. So, my question is was it "Fly Strike", a poopy butt (her butt has always been poopier than my RRs), or something else? My 3 hens are completely protected from predators in their enclosure (except for rats, I suppose), so it's definitely not raccoon, fox, dog, or any other large predator. Any ideas to help me prevent this in the future?
