my broody hen has been sitting on 8 eggs for 18 days, this morning i went out to the coop to collect some eggs for breakfast and she was in a different nesting box. there was a hen on the eggs just not the broody hen, my broody was in a nest box with only 1 egg in it? what happened!?did she get up for breakfast and another hen stole her nest? did she give up with only 3 days to go? What do i do? i tried putting her in her old box and she just got out and flew the coop!are my little ones doomed?
