Okay. Hopefully you are able to understand me in this post. I have tote brooders. One kennel cage as a brooder. The kennel contains 20 chicks. All alive from breeder. One large tote contains 14 chicks, all alive from a different breeder. The longest tote, had smaller hatched chicks, of which I took out of The same breed and placed them in a small tote. Another large tote contained 9 chicks from a breeder. All are lined up against the wall, inside my home. Heat lamp on, never to close. Turned off when its too hot to lower temp. On to raise. The holes on the totes are 3/4 inch the entire top of the lid on two totes. With holes on the top half on the side x2. One tote top is replaced with cage wire. Bedding changed regularly. Fresh water twice, sometimes three times a day. Fresh starter feed morning and as the day goes on. Now, I can't see anything wrong, can you? However, chicks are dropping like flies. I find one every morning. Lately, yesterday, total died 4. This morning and just now, 2. I can't see the reason why. At 1st, I thought that the other chicks squashed the one that died. Now, is apparent that they are just dropping dead. I've checked their droppings, poop. All normal. But I still took precaution and bought medicated feed. What is it that I'm doing wrong? I did electroltes. Still, dying. Can anyone give any other advice on what could be, or can be done? Any and all comments welcomed.
