just picked up 5 assorted bantams probably about 5 days old. One seems much bigger than the rest and I suspect it’s not a bantam, however, she’s not doing well today. This is not my first time raising chicks. I have a large container, ventilated on top, shavings on the floor and a red heat bulb at a constant 90-95 degrees at one end. Free food/clean water at all times and plenty of space to roam and get out from under the heat bulb. That being said my other 4 bantams are doing perfect. Chirping and scratching about. After about 3 days I noticed my big girl sleeping on her side, breathing pretty heavy, and when I went to pick her up she’s limp but very much alive still. Even let out a chirp. I’ve removed her from right under the heat in case she was too hot, and offered her some electrolyte water but she will not drink. No one is picking on her or anything but she will not snap out of it. Occasionally I see her spaz like she’s trying to get up but cannot stand at all. What should I do?
