I found one of my pullets slumped over behind the food bowl this morning and picked her up to see what was wrong. Discovered fly strike. Had never heard of it until today, but a quick search tells me its a common chicken disease/injury. Without know what to do, after going in and reading all the posts about this, it sounds like I did the right thing. Washed, sprayed, picked, soaked, picked and flushed. Sprayed with Vetericyn once i was done. There is now a pretty large open wound where they got under the skin (you could lift the surface of the skin and see in about an inch, but it does look like its only on the surface layer. The pullet on the other hand looks close to death. Alive, but can't really hold itself up. I've been force feeding vitamins and electrolytes. She is no where near close to wanting to eat anything. My question is, can/should I give it a Tylan 50 shot? I assume there is a pretty good infection going on in there? any help you can provide would be greatly appreciated. update: She passed not much later. I think she was too far gone. for future knowledge and for the health of my flock, is there always an underlying reason the flystrike happens in the first place? Should I be looking for other diseases?
