We got our first chicks 3/23, they all seemed well at the feed store and we were told the 3 light brahams were about a week old. Last night one of them suddenly started going crazy scratching at its ear, flopping about, and screaming cheeping. We read here on the BYC forums and called a friend for ideas. Thinking it might be mites even though we didn't see anything, we put olive oil on the ears and neck, held it to keep it warm since it seemed a bit cool, and rubbed its ears (it seemed to like that), and it calmed down and slept. We discovered that its crop was quite large compared to the other 2 same breed chicks and it seemed irritated if it was touched near it. We read about impacted crop and thought perhaps it was this too. We gave it some warm water with a bit of apple cider vinegar in it. We massaged it's crop. We gave it some yogurt with olive oil added. It seemed to like all that and rested. About an hour later, it's crop was smaller, it wasn't scratching and it seemed do be doing well. We put it in clean bedding in a box separate from the other new chicks. We and it went to sleep. Today, we checked on it right away and it seemed to be doing well. It had good looking poop, seemed quite active, was eating and drinking well, and not scratching. Throughout the day it looked fine. About 10pm, it suddenly went crazy screaming, scratching, flopping about, and again it seemed to have a very large crop again. those 2 unrelated(in our minds) symptoms again. We read that rubbing alcohol might kill mites so in case that was part of the problem we q-tip bathed it in that and then kept it warm by holding it and putting a heating pad under it. It still intermittently went crazy trying to scratch and flop around. We again gave it warm water with a bit of apple cider vinegar in it. We massaged it's crop. We put olive oil on the ears and neck, held it and rubbed its ears. It calmed down and slept but if we stopped running it's ears it woke up and if we move our hands away it immediately starts scratching & screaming. We so don't know what else to do . We can't sleep with it in our hands. We got these chicks for eggs and pets and this isn't a good start to our chicken adventure. We hope someone is still up and can give us some ideas.
