My serama hen started acting strange about a week ago. She couldn't walk right, when she did walk she would kind of use her wing as a crutch. She was basically just acting really weak. I was mostly figuring it was due to her being so tiny and laying so many eggs (5 in 6 days). I had read about mites on here, but when I checked I hadn't seen any. Finally a couple days ago I was checking her over again, and I saw a little brown mite crawling near her vent. I picked up some 5% sevin dust and dusted both her and the roo, and cleaned out their cage and washed it out. I also picked up some vitamin/electrolyte mix and have been giving her that to see if that would help her spring back from the mites. Well here it is 2 days later, and she still doesn't seem to want to walk and is still acting pretty weak. She eats like a pig, drinks, and poops just fine. She seems to be very alert, but i just seems like she just doesn't want to walk around. We have 2 brooders of chicks, one right above the serama's cage, the Serama roo living with her and no one else is showing any signs of whatever this is, so I know it's not some kind of disease. Just curious as to what you guys think it is. If it was just mites and being tired from laying so many eggs (she layed her 6th yesterday), am I looking at a long recoup time from the mites, or is there something else I'm missing here?
