Hi, a little new to this website but thanks so much to anyone who can help! I have a rooster around 5 years old. Last Friday I noticed he was acting funny, sort of huddled and droopy and not really active like he was sick and had a fever or something (he kept wanting to stand under the sun) but he was eating and sort of walked around and drinking a tooon of water. The few days before, we had a lot of rain and it got kind of cold so I thought he might have caught a cold or something. No runny nose, normal breathing, but was very thin. I dusted him for mites and put him in a cage somewhere warm with food and water and after a few days he was getting better and getting restless in the cage so I let him back in the coop where he seemed to be doing fine. He was never quite as springy as he used to be, though he was getting heavier and stronger every day and got quite close to normal conditions. Today, (Thursday) just an hour or two ago, I was feeding him and my hen. He seemed fine when I first brought him food (hopping around the coop, etc.) and he started eating fine also. I turned around for a second and I turned back and he was lying on the ground but eating the food that was around him. I thought he may have fell and twisted his leg or something so I lifted him back up, but he stopped eating and just stood, not moving and started getting really droopy and puffing up his feathers. I didn't know what was going on or what to do but I put him back in the cage somewhere a little warmer. He didn't touch the food and water I put with him but instead started getting droopier and droopier and now is literally lying on the ground with his eyes closed, looks really bad and sick. He is still breathing and moves his head a little and every once in a while shifts his body slightly, but that's it. This all happened in a span of maybe 30 minutes or less. It's not particularly cold today (low 70's right now) and it rained a little bit (but not hard) and it's a little windy. He's indoors in the cage now. I put little aspirin in his water because I was getting desperate and thought it may at least help with pain relief or reduce his fever if he had one, but he hasn't drank any of it. In the last few days, I've fed him and the hen rice (which they've been eating as a major part of their diet for years), vegetables, and the occasional leftover meat etc. I've put some diatomaceous earth in their food and water (something I do every once in a while to deworm them) and the two of them found a roach nest the other day and ate them all up I did notice, in the first few days where he was in the cage, he pooped less frequently than I expected him too and it either came out in little pellets or once, after he ate a lot of cabbage, as a big runny heap. Does anyone know what is going on?? Or what might be wrong with him?? Or if there's anything I can do?? Any help is appreciated thank you so much!
