One of my hens has a VERY bad case of mites. She is sick and lethargic as a result. I have dusted her and bathed her vent area which was very poopy. Have also put Ivermectin on her over the past couple of days. Has anyone bathed their bird for mites? This may seem extreme but the mites and their dirt is very heavy. The other poultry do not have this problem. Somehow she has got very run down and succumbed to the mites. I think everyone of them is on her and barely on anyone else! Would appreciate any input.
