As far as we know he was fine when I took him to my car. I noted he stunk really bad, but assumed he'd gotten pooped on by someone on the top roost. He rode in a fabric pet taxi with several chicks. They are all Crested Cream Legbars. Beyond that I didn't notice anything unusual. When I got home I put him into a kennel with water and food. The chicks are all fine, but I noticed something slimy on his beak and figured he'd gotten poop on his beak in transport. Came to check on him a few hours later and saw him shaking his head and scratching. I looked closer and saw something like a flea on speed run up out of his head feathers and run in a loop around his comb a couple times. I immediately took him out and rubbed poultry powder into his feathers. He was very compliant and didn't fight anything I did to him. I put him back in the kennel. Came back out a few hours later and he was still shaking his head occasionally and now his head was drooping and eyes were half closed. I looked closer and saw he had some slimy stuff dripping from his nostrils and beak - looked like mucus. I realized I had not seen him eat or drink. I took him in the house and put him back in the fabric kennel to keep an eye on him. I mixed up some probiotics and electrolytes in his water and tried to give him some in a dropper. He had no interest but I did get some into him. He'd look ok and then start drooping, eyes fluttering and head twitching. I kept forcing a little of the water mixture into him throughout the day. Each time I would scrape some more dried on mucus from his beak/nostrils. I opened his mouth to see if I could observe anything stuck in his throat or anything. I saw nothing but one little piece of grass on the inside of his beak which I removed. This morning he is still alive thank goodness, and I am letting him wander around the living room a bit since he wanted out. But he still doesn't want to eat or drink and the tips of his comb look like they are turning black. He mostly just stand sort of hunkered down, and looks droopy. I scraped more dried mucus from his beak and forced more water mixture into him. His poop is mostly the white which I think is the urine. I am afraid he is dehydrating himself and not sure what else to do. Is this a heat injury? It was in the mid 90's yesterday when I transported him. He was in the rear of the car, the A/C was on and the car was comfortable to we humans but may not have circulated to the very back too well. The previous owner examined the rest of the breeder pen and no one else has any signs of any illness. Thanks for any help!! Got some pictures, not sure how good they are or if they will help but worth a shot. Couldn't really get the mucus to show up but you can see some of the blackening comb.
