My 1 yr old girl has been wobbling and progressively worsening since Easter, ad her face has gone pale to white. She gasps all day long. Her crop seemed puffier in the beginning just a bit? So have I have given her drench and today used electrolyte vitamins. BUT I also gave her some Nystatin Oral Suspension a couple weeks back for 2 days. I did not have a dose for chickens as it was for my kiddo but I'd say I syringed maybe 5ml or a teaspoon in with hubby's assist every time she gasped. After that her face reddened up again and she walked MUCH better and her tail went back up for a day or so then back to the latter and now worsening, so I will try that again and see how it goes. Her crop has not been distended and she is much more frail now. She eats well but cannot seem to stand up fully and flops so she is in quarantined 4x4 safety area within the run in the day and in her own 2x 4 nesting area in the coop at night because the others jumped her at the start once I removed her overnight and seem to want to keep at it. Oh and she stopped laying about a week ago but I don't feel an egg so maybe she's just to frail to make any?
