My broody hens hatched out several baby chicks over the past month and one of the last few (about a week old) all of a sudden has been acting very sick. Let me preface by saying this: it stays in a brooder with about 15 other chicks of various ages (oldest is maybe about 4-5 weeks old) and yesterday, I didnt plug the heat lamp back in after watering them. It's been almost 90F here and it's in the barn so draft free, with a bunch of other chicks. I came back several hours later in the evening to feed and water them again and it's hunched up, wings are kind of puffed out and it was very lethargic. I brought it into the house, on a heating pad set on low/medium and made it some honey water and after that, an electrolyte recipe for chickens that I found online with molasses, baking soda and water. Its since been going back and forth between perking up, even walking around and eating and drinking by itself but then all of a sudden, it will lay on it's side again, looking dead. It consistently has its eyes closed, unless I rouse it or it eats/drinks. The other weird thing is, the feathers look really "split" or something. I'm not sure how to describe it. The people at the feed store said it sounded like it got too cold but why isn't it recovering all the way then since I warmed it up and got some water and food in it? They didn't think it was coccidia... Any advice what else I could do or what this could be? My 4.5 year old daughter is quite attached to it, of course. Oh, I picked up some rooster booster electrolyte/vitamin and gave him some of that with a dropper and it drank some by itself too. But has since then gona back and forth between laying there, looking like it's moments away from death, and perking up a bit. Thanks in advance!!
