My hen was broody for 23 days, nothing....cracked all the eggs and there was nothing in 7, but the last looked to be about a week premature.I marked and dated all the eggs under her, so by date, I kept up with them. Weather has been odd here so I attributed that to the loss. Last one I cracked was viable, but a week to soon, so in essence, I killed it. I know, horrible but I found out the kids had given the hen an egg I didnt know was in there and when I candled, it was too dark a shell to see through. I have offered the hen a new batch of 5 fertile eggs, and she took them and squawed and settled down on them...will she continue to try and naturally hatch after being broody for so long already? Is it safe for her health to allow her to brood again for the desired amount of time to hatch the new batch???
