my first time broody hen diligently sat on eleven eggs. Four hatched on day 21. She moved to next nest box and eggs were left all over the place. I put them near her and she tucked them under her and continues to sit. It is early day 24. I heard peeping of one egg yesterday when moving them. Any chance they might hatch? Should I intervene? Should I candle? I don't have an incubator, so if I start a pip hole, do I then place back under mama? Thanks very much. It's tough to hear peeping, but not see any progress!
