Please help. We have five chickens that are about 2 3/4 years old. One of them cannot stand or walk. It's keel is protruding and she has trouble eating and drinking, she mostly has trouble drinking though. She will only eat her food if it is soaked in water first. One of her legs is pulled back while the other is forward. He comb is not too discolored, it just looks like it has a bit of purple/blue at the tips which may just be from the cold weather. Her poops are a yellowish greenish and don't happen very often. Her toes are also curled up. She can't even sit correctly, she can only sit lop sided. She has trouble keeping her eyes open but they look normal. She has been isolated from the other chickens while this has been going on. This has been going on for a couple of days now, and we are worried these will be her last days. Somebody please help! We are all very worried and scared for her. Is there a broken bone? Does she have Marek's Disease? Is she just sick? What can we feed her to help her get better? (Also, we bought electrolytes to see if it would help. We have also been keeping her very hydrated with giving her 7 milliliters of water every 30 minutes to an hour. )
