We have a Buff Orpington that is always broody. We decided to get her some fertile eggs and this weekend the temps dropped to -8F. We put the eggs under her Saturday afternoon and Sunday she got off the eggs for a few hours to go outside. It's typical that we finally get her the eggs she wants and she gets off the eggs for a few hours. My question is: Are we wasting time and her energy now that the eggs were at low temperatures for a few hours? Should I just give her new eggs? They only cost a $1 each and she is sitting on 7.
