This is my third time brooding chicks. I've also had two other flocks with a broody hen. I've never lost chicks before, but this time they don't seem to doing as well. They shipped me 40 chicks, one was DOA. About day 3 I saw one kind of gasping for breath. I didn't do anything, and at the end of the day, she died. At that point I saw that the chicks were piling up on the edges of the brooder, near the lamp, but not under it. I put a thermometer on the ground under the light, and it was over 100. So I switched the heat lamp out with a 100 W bulb. I added electrolytes to the water. I keep cornmeal in the food to help with pasting. Yesterday was day 7. Another chick died, his body temperature seemed cold, but he was dying so maybe that was why? He did not do the gasping thing. He was noticeably smaller than the other. Like he had not grown. I increased the size of the brooder and added more feeders and waterers. They are eating and drinking well. They sleep all together under the light bulb. I just went out and found one gasping. When I got him out he seemed hot. I'm just holding him right now. He cooled off and quit gasping. I don't understand if they are hot why they don't move. I've given them enough room to get out from under the bulb. One nostril seemed crusty. I cleaned it off. He's cheeping a little. He pooped, and it was chocolate colored, the consistency of snot, and stinky. Trying to tell you everything.. Does it sound like I need to make some changes? I'm using unmedicated feed. Should I switch, should I add antibiotic to the water? I know it is normal to loose some, but I just want to make sure I'm not missing something.
