This is a brahma chick that is the last one and still not hatched, it is only day 21 but all the others hatched on day 20...also humidity dropped to 30% because I was afraid to open the bator during lockdown and add more water! Shortly after finally deciding to open it and add more today the last unhatched silkie died!!! The brahma chick is still breathing and I cracked some of the shell away with a tweezers, but the chick hasn't continued to hatch for 12 hours, what should I do? All the other 9 chicks and the shells in the bator are so crowded and the babies seem hot - they keeping hanging their mouths open...
