I have a 3 year old hen that had mites about 2-3 weeks ago so we put sevin dust on her head and in her coop most of the mites went away but I noticed 2 days ago she seemed a little off- the dust got kind of cakey so i washed it off picked as many of the mites as i could off and after she dried put so more dust on. the next day her skin around her eyes and cheek area seems a bit swollen and she is lethargic but still moving around and eating and drinking but not as quick as she normally does. then today i noticed she had like a mass of poop stuck to her so i cleaned that all off but she still seems lethargic to me..She has only laid like 3 eggs her whole life and that was about 2 years ago. We do give her about 15 meal worms a day and she eats scratch. her face is still puffy she is lethargic and i haven't seen her poop. not sure if she is egg bound or what? please help? Thanks!
