I just don't know what to do with my Silkie hen. I had posted about mites awhile back. I thought I had them under control but I guess not. She's the only one out of the whole coop who seems to have them. I thoroughly checked each chicken & couldn't find a single one. She was so bad that she was brought in the house twice. 2nd time around she was thin but didn't see many mites (reddish fast moving bugs) but I made sure she was eating and drinking fine. Well she was doing so good that for a couple of days I didn't 'examin" her as good as before. 2 days ago I noticed her eyes were crusted/swelled shut and she lost alot of weight. I saw her eating/drinking though. She had some mites around her vent and covering her head only....nowhere else on the body. She's already been treated with the poultry dust for over a month now (along with the whole coop), plus a couple baths (today as well) I noticed her feet are hard as rocks! She can't move her feet or her toes. They were badly bitten before but this all happened so fast! What could be wrong with her feet? I'm getting so frustrated and this poor girl is not doing well. She's soooo sweet and she doesn't seem to be giving up but I don't know if shes suffering. Can somebody please help me because this is not working, what i'm doing. Her eyes get crusted shut just about everytime I wipe them off. I put some Vitamin E oil around them hoping it would work.....her feet worry me. Any help PLEASE!
