The one that's been broody for more than a month, and the one that became broody today and stole first hen's eggs. 1st hen moved to another egg box and sat on nothing. 2nd hen is a cow, I guess, and cracked one of the 1st hen's eggs, so I took the opportunity to find that after 8 days, the eggs had not developed due to the heat. I just placed ice packs in each of the egg boxes and hope that keeps them out of there. I thought it was weird that 1st hen was never de-feathered on the tummy, but 2nd hen is.
