Two of my hens have been broody. The first started sitting on the first egg 23 days ago, the 2nd a few days after that. When they get out some other hens have popped in and laid more eggs, John counted tonight, they are both on 14 eggs each. There has been a night or two that the girls have left the nest unattended at over night. Should I just leave them? Take them out and incubate them? Toss them? They are all dark brown eggs and I have tried candling them, but just not sure on their status.
