I'm having difficulty helping my 5 year old Barred Rock hen, Maple. She's been ill for quite some time now. I noticed about seven weeks ago that she was getting thin. Previously, she was very healthy. She free ranges and this is before all the snow came- my flock is mostly isolated in their coop right now and as been that way for about a month. (She's been sick with this since before the snow) She has chronic diarrhea. I don't think that it is greenish, though maybe at times it is. Today, her poop was watery, with yellow white slime, but regular brown poop color droppings in the yellow white 'slime'. I'm guessing the white is urates? Not sure. She has up to this point been fairly active. You would not have known anything was wrong with her unless you picked her up. She was moving around just like the others and eating just like the others. There were times in which I would catch her sitting with the other sick hens I have. (One just died recently of egg yolk peritonitis- I did the necropsy and affirmed this). She does not have any lumps in her abdomen. Everything seems normal. She was gassy this afternoon it seems. I heard her let out a large fart and after that her stomach was gurgling. She doesn't seem to keep her eyes open- the bottom eyelid is half closed over her eyes. The eyes don't seem to have anything wrong with them. She just seems very tired, weak. She is eating, but I noticed she will not eat the whole bowl of food. She will stop after a while, which is not really chicken like. Normally, a hen will eat everything you have to offer. I checked her crop and it does seem as though it is emptying. I noticed some time ago sometimes she has difficulty swallowing it seems- she will swallow its its as if she needs to press the food down the remaining passage- she wrenches her neck to get the food down. She also seems dehydrated now- Her comb is dry and not supple. I have treated her for worms, used ivermectin then Wazine- no change. I have given her duramyacin 10, sulmet- no change. I have given her lincomyacin- no change.. and I am now thinking about trying some bacitracin methylene disalicylate- yet I'm not sure about the dosage. I'm really out of ideas to try. Her biggest noticeable thing is her weight loss. And the fact that she has a ravenous appetite, but then kind of stops after a while. I've looked up so much stuff on the internet and in my books and really I'm at a loss. I'm just wondering if anyone else can maybe give me some advice on what to try or what they think it could be? thanks in advance for any replies.
