Hi there, My 9 month old Wheaten Ameraucana, Wickham, is suddenly lethargic this morning. Yesterday he was acting completely normal. This morning my husband found green and yellow diarrhea in the coop (which is definitley Wickham's as I've found some stuck to his butt feathers). I've checked him over for parasites, but didn't see any. He has clear eyes and nostrils. I offered him some scrambled eggs and he ate a few bites ravenously, but has not finished it. He's inside a carrier inside the house. I haven't seen him drink in his own, but will give him some with a syringe in a little while. I've made up a solution with Durvet's electrolytes in it. I can't imagine what's wrong with him. His three girls seem perfectly fine and are pecking around the yard as we speak. I did do a couple things out of the ordinary yesterday. Around 4pm yesterday, I gave them some watermelon which they haven't had since summer. Wickham ate some, but not a huge amount. One of the girls ate a ton. I also dusted the coop and nest boxes with DE, which I also haven't done in awhile. Could either of those things cause a problem? The only thing I can think of is that maybe there are mites in the coop. I did see a couple tiny brown bugs hanging around the nest boxes. AND Wickham does have a number of small black spots on his comb. Mites are the ones that hang out in the coop during the day, and feed on the chickens at night, right? I will have to check the other birds tonight. But then, why would only Wickham be affected? If anyone has any insight, I'd really appreciate it.
