I just checked on the hen who has been on an egg for almost a month. When I picked p the egg, the shell cracked - the membrance did not rupture, though, and I cold see a fully formed chick inside. But, I couldn't tell if it was alive. I immediately put it back under the hen. What do you think? Has it been too long and would the chick be dead after 21 days? Did the cracking shell seal the deal for no chick? (entirely my fault - 1st time I have tried to hatch my own chick in the 3 years I ahve had hens) ANY HELP WOULD BE SOOOO APPRECIATED!!!!
