I guess I"m scared they have worms because I am extra reluctant to treat them (with chemicals) for worms. I am about to lose my third RSL in three weeks. They look poorly and are missing feathers. I see no mites or fleas but they do look like terrible birds. They have looked poorly since about March but most have grown back fluffy new feathers. The only thing about my hens is their feathers and then when they die, their very very red inverted vent. To me, their eyes look fine and so does their comb. Any ideas on what might be picking off my hens week by week? p.s. it takes about two to three days for them to die. I will be culling this one so as to not prolong her death.
