You would be amazed, I had a game-ish black hen go broody in a 5 gal bucket on it's side next to another one & when the other hen laid in the bucket beside her she cleverly patiently rolled the new egg over to her pile, it took me a few days to catch her in the act & then she had put so much work into I just let her keep the extra eggs to sit.We set 28 eggs this morning! Here we go, round two! We also have a broody hen that has been sitting on eggs for 7 days now. I have this strange suspicion that she is stealing eggs from the other nest boxes. Everyday there are more that I have to remove. How would a hen "steal" eggs. I haven't seen any of the other hens laying in her box. She hardly leaves it herself.
