She's about 3 years old same weight as the others. Noticed yesterday she was separating herself from the others laying down under a fern. Kept an eye on her all day and seen she was barely able to walk so I put her in our sick bay with probiotic water gave her a squeeze of nutridrench and fixed her a plate of scrambled eggs yogurt and some cut up fruits. Checked her crop and it was full and squishy, this morning it was empty she hadn't touched her food and I don't think she drank anything looked like she hadn't moved at all. I fed her some probiotic powder from a pill and some olive oil washed it down with a couple full syringes of water and had her eat some boiled egg. Brought her inside for an epsom salt soak for about a half hour currently she's drying by the fire. I should also note it seems she's losing a lot of feathers there were a ton in the bath and when I was blow drying her even more yet. Any help would be greatly appreciated
