I'm mostly posting this for a lesson for everyone. A little over 2 weeks ago, on the 12th, one of my hens had flystrike. I found it early, gave her multiple baths with betadine, & put Vetericyn on her daily. But I really wish I hadn't believed a good amount of the sites I read that stated she didn't need an antibiotic unless she seemed sick. It never fully healed, it still had a scab on it even after 2 weeks. Nothing oozed from it, it didn't omit a bad smell, she still would eat & drink, but I think that it either else took too much out of her physically (she also started going through her molt), or she did have an infection that didn't show signs. She seemed fine this morning, even running away from me when I went to check her. But tonight she was dead on her side ..... only odd thing was her neck feathers stood up (like she had been angry to scared) & weren't flat down. She was in a stall, no predators could have gotten her, I don't really have any other explanation. If this ever happens again, I will be putting them on antibiotics ASAP - even if other sites don't recommend doing so.
