I checked the last marans egg that I put under the other broody. no sign of life. I yesterday candled it and saw the air cell and a dark part, nothing moving. I decided to shake it and it was rattling inside. so I decided to crack it and see what went wrong. I slowly cracked it and a head and 1 toe popped out and the chick chirped. there was little blood but not bleeding. unfortunately almost all the shell is gone. I put the chick under the lamp and wait. the yolk hasn't been absorbed but I didn't detach it. it is sitting in the membrane. I put the kitchen towel over it and I wet it as I don't want it to cook under the lamp. but I don't think the chick will make it.
