I have 36 chicks, all 5-6 days old I got from McMurray, they arrived two days ago. Upon arrival all seemed surprisingly chipper and healthy and took to eating and drinking extremely well. According to my infrared thermometer, the brooder is 96 degrees on one side and 84 on the other, and during the day they're all spread out, though at night they seem to all snuggle together in an area about halfway between the two temps. They are in the house and I haven't changed my thermostat, it's not a drafty room at all (even if it were the lows at night are in the 60's down here right now). The first night home I woke up to a dead chick, he looked as though he had been trampled overnight. No sign of pasty butt or bloody poop anywhere. I kept a close eye on the rest of them the next 24 hours, sure that I had just missed a symptom. This morning at 6 am when I awoke all were fine, running around and taking advantage of the fresh water. Not three hours later I check on them again and there's another dead chick, seemingly trampled with no obvious explanation why. I've got them on medicated feed and will be going to purchase some electrolytes and antibiotics when my husband gets home in a few minutes. Any ideas as to what is going on? Are they suffocating each other snuggling? I'm super confused. I don't think it's cocci, as there are no symptoms and no odd stools? And a second problem I believe is unrelated to the first two deaths: I have a little speckled sussex that has been much smaller than the rest since they arrived. Actually, she and my golden laced wyandotte were the same size, but the wyandotte pullet is already growing and pulling ahead. The first 24 hours she was doing great, eating and drinking with the rest of them. Today, though, she's lethargic, falling asleep on her feet. I've given her water through a syringe and she sucks it down but won't really move to drink herself from the dish. I can't get her to eat. I separated her from the rest because she was just standing there letting them peck at her. She's actually in my shirt, nestled down in between my boobs right now, sleeping. Her breathing is normal, and her poop is watery but just like she's drinking too much and not eating enough. What can I give her to perk her up or is she just a goner?
