Ok firstly, I appreciate all of you who helped me on Friday evening on this board. What I thought was cocci or worms ended up being maggots. My Barred Rock hen had been severly eaten away by maggots on her hind quarter. My wife and I administered 2 hours of saline baths and I tweezed hundreds of maggots away but she was too far gone and we culled her to stop her misery. Poor girl. I can't believe how cruel the maggots and this condition is. Now I still have a flock to think about. What went wrong? How did maggots start attacking our hen's hind quarter? What can I do? Thank you everyone.
