Today is day 19. My husband and I have had 3 bantam chicks hatch successfully. One EE mix pipped, started to zip and died. Once removed from the shell we discovered its head was turned to the side and looked as though it could not turn it forward because its thigh was in the way. We have had one more EE pip along with one Comet/Brahma mix and one Leghorn/Brahma mix. I know this is really early for all this activity. Our temp jumped up to 104 for a few hours on day 11 and we kept the humidity around 50-55 the first 18 days per incubator instructions (maybe I should have just thrown them in the trash) I worry they grew way too fast and will not make it. On the start of day 18 some of the air cells looked smaller than others. I wish I would have left those in the turner a little longer before lock down. W have made sure the humidity is 70%. How long should we give the pipped eggs before assisting. I would hate to see anymore die if I knew there was something we could do.
