I have lost 6 chicks and 2 adult chickens. Now I have an adult chicken with weird wormy things all over her back half. They are not just in the immediate vent area, but in the feathers out around the back third of the chicken. They are dropping off her at an alarming rate now that I rinsed her thoroughly. Here is what they look like. Help me, please. I thought we were dealing with cocciodosis and been treating everyone with corid. Now this girl is sickly and I find this infestation. I have captured and popped over a hundred of them. I don’t think they are standard maggots (seen many). Maybe from some other kind of fly? What do you think?
