Hi all, we have a young broody hen who was sitting on all of our hens eggs (five hens all up). She had a huge amount and after some research and candling we've managed to cull a few that weren't growing. We estimated day 21 to be last weekend, it's now the following Saturday and no chicks, although I can hear one tapping and scratching the shell with no pipping visible yet. Considering it is obviously possible that we have no clue how old the eggs are, it is hard not to worry and try to help. Is there anything else I can do to check progress or health? I'm suspecting eggs have been added after she started to become broody, resulting in the long delay... Help please!!!
