background: i have five 1 1/2 year old hens and five 6 month old babies that are free range birds on an acre of land. two months ago i lost one of my hens. she was dead in the morning with no signs of trauma. she was nice and heavy. i buried her because i did not know UC Davis does chicken autopsies. a month later i lost a rooster (5 months old). he was very skinny and the autopsy came back that he died from secondary infections because he had coccidiosis. i treated the whole flock with sulfasol (my feed store did not have corid). after this, i took my "special chicken" (born with a broken neck) to the aviary vet. she came back with a clean bill of health. then one bird from my neighbors flock died (autopsy came back with mareks). the neighbors flock and mind tend to visit. my neighbor lets nature take it course so i am treating her flock too (22 birds). next i lost another one of my birds (very skinny little one). i am waiting for the autopsy to come back but the preliminary one came back saying she had no fat on her body (none at all!!). i can post the autopsy if people think it would help or be interesting to read. now: i have three birds in my laundry room (chicken infirmary) in rabbit hutches. one from my neighbors flock. treated her with sulfasol. no improvement. while she was walking on my floor she pooped and i found a round worm in the poo (3 inches and looks like angel hair pasta). treated her and both flocks with wazine. she is eating and drinking very little. she still feels good. she has diarrhea. birds 2 and 3 are from my flock (6 months old). they are dangerously skinny. they have a good appetite but seem tired (need naps throughout the day). i just ordered corid which should be here tomorrow. both of these birds poo looks ok but do tend to keep their heads down instead of perky. i am a new to chickens. everything i know has come from reading other peoples post. i have tried everything i can think of and i am still losing my girls. any suggestions would be greatly appreciated!
