About a month ago, I had a hen get bitten by a snake. I didn't actually see it happen, but I noticed her limping that day and took her off the roost at night to examine her. She had two deep and distinct fang marks with what looked almost like fat around them. By fat I mean it was this yellow, greasy, squishy but tough substance . Well, I went to the feed store and bought some betadine, which I cleaned the area with. Then I noticed that her foot was swollen, hot and smelly. I cleaned that too and kept her in for a few days with a mix of layena and cracked corn for food (I didn't have any yogurt without artificial sweeteners or anything...). Eventually,she stopped limping and looked better so I put her back with the flock. About a week later, she resumed limping, became lethargic (sneaking off to a patch of grass for a nap when the others were foraging), and lost weight fast. I brought her inside again and although her leg isn't hot anymore but it has a big hard lump on it. She smells really funky, and her stomach looks pretty gross. She doesn't feel as heavy as she used to, and she just downright looks like she feels crappy (chalky face, closing eyes a lot). I have given her some natural yougurt, strawberry bits, and gerber baby finger food (crushed up for tastiness). I sprayed some colloidal silver (if anyone else knows about that, do you have an opinion on it?) in her water and also added Sav-A-Chick electrolytes to it. I am really worried for her so if anyone can help please do! I can post pictures tomorrow after I get back from school and ballet if it would help.
