EDIT: I am updating whenever I can, and it doesn't seem like Bo's doing much better tonight than where he was yesterday. Any help or good words are appreciated! END EDIT My dearly beloved rooster, Bo, is currently not acting like himself. I woke up to check on him since when I last went to sleep he had fallen off his perch and was gaping a little. I figured his gaping might have been because he hit his keel bone against the ground or something since after holding him a little while, he seemed fine, so I put him back on his perch and went back to bed. Upon waking next, I saw him on his perch, but gasping. Further investigation showed he wasn't gasping so much as... burping? When I pulled him out this time, he didn't respond with nearly as much energy as he usually would have, and just kind of fell into me - not limp, but not as supportive of himself as he would usually be. Sitting in my lap, he let out a "burp" right into my face ( which sounded like a little puff of air ) and it was very fruity-smelling, almost sickly-sweet like the beginning of a rotting carcase. I palpated his chest a bit and when I gave his crop a little squeeze, it gurgled, so I squeezed it some more until it stopped gurgling, and he's stopped gasping. His breath still smells sweet, and he's still not feeling well. He's just sitting here next to me with his eyes closed, and usually he'd be watching me type, and the screen, with interest. He also tried to preen when I set him up on the bathroom sink to no avail. He couldn't even reach his oil gland, ceasing trying to get to it when he had his head over his wing, then just tried to preen some leg feathers, but had difficulty with that, so just stopped, sat down, closed his eyes, and that was it. He has JUST started shaking, tightening the muscles over his whole body for a few seconds before releasing. I have covered him partially with a towel. Some of my house mate's hens are making noise outside right now and when they do, Bo perks up and listens, but that's about it. His stool has also been more watery than the other chickens, and he has some pasty-butt going on. Bo is a standard-sized 3/4 Rhode Island Red and 1/4 barred Plymouth Rock. His mother was a Blackstar and his father a Rhode Island Red. He is my best buddy in the whole wide world. So here's a run-down of symptoms as they are right now: * semi-lethargic * won't stand, prone to falling off perch * shaking * intermittent muscle tension ( similar to when my hens are about to lay an egg and seize up their back muscles and stand at about a 45* angle - his cloaca free of debris ) * feathers on back of neck raised ( which means he's feeling anxious and upset ) * mild pasty-butt BEFORE squeezing crop and releasing gas... * gaping motion * hissing sound when gaping * sickly-sweet smelling breath Things that have happened recently... Friday afternoon Bo and I went for a bike ride. Bo rides with me very, very often, but today my bike was in a bit of disrepair, so he had to be tethered to a sort of baby-bag thing. It keeps him close to my chest so he doesn't fall into the bike tyre or fall off entirely. My other four chickens are fine with this. Not Bo, he wanted to ride on my handlebars. He's allowed to ride my other bike on the handlebars since that bike's handlebars are much, much higher, so I can use his leash wrapped around my hand to keep him safe of the tyre. So along the way, he jumped out of the bag, and landed on the top tube of the bike - no big deal, that's exactly what the tether is in place for. I stop at a bench, pick him up, and while working with him to become familiar with the bag and new form of transport, he tried to jump again and got his toe caught in my nose. I picked him up, hugging him with both arms. I've found that a gentle pinch on the back of the neck helps to calm chickens, but my hands were tied up, so I gently nibbled his neck. He was relaxing, and then seemed to remember his toe was caught and yanked it right out of my nose. I bit his neck - but mind you, only the loose skin on the top. I had initially THOUGHT this was the culprit of the succeeding events, but the vet told me otherwise. After this Bo, predictably, freaked out. I was trying to hold him steady and calm him down ( which the doctor then told me may have accidentally suffocated him ), and this went on for about five minutes before he collapsed. His head was lulling, his eyes closing. I patted his chest and he perked up momentarily, then would lull again. I biked him to the nearest veterinary clinic who pointed me to another clinic, but before leaving they gave him some water and he perked right up. Upon arriving at the next clinic, the doctor saw him and said that Bo had suffered from suffocation followed by shock, which water usually does wonders for, so we encouraged him to gulp down as much water as he could, and we saw dramatic improvements. The doctor then told me to put Bo strictly on a dry cat food diet since he was a bit thin, or mix it with 50% chicken feed if I really felt I wanted to. Bo and I then hitched a bus down town where an art show was taking place so I could price some art, and the whole time he seemed his normal self again. Brought him home, and he wanted nothing more than to go see his hens, as usual, so I dropped him in his coop with his girls, and he immediately went about his business. NOW, I think I may have stumbled upon a culprit here... When I got home, the chicken's water was nearly empty, so I took that away and gave them some food while I went to fill up the water. I had been trying to give Bo water throughout the day, and he sucked up water when I offered it to him whenever I was sitting or standing in one place, as he usually would - he just loves drinking out of the water bottles I have for my chickens, and since he was young he seemed to find a particular enjoyment out of the click-a-click of the metal ball at the end of the tube. Could all of this been attributed to me giving him access to food before water, and thus creating a blockage in the crop, or is it something else?
