Okay so I am new to this I have a Broody hen and she is currently sitting on six eggs. She started with 16 eggs this morning she cracked one and it was bad. So I opened 9 of them today (day 25) and found two chicks. I'm not sure how to tell if the we're alive before I opened them or not. Chicks seem to be only at about day 17 at the max they had feathers on their bodies but still quite big yolk sacs however. I'm hoping I didn't make the typical beginner's mistake and kill two babies. How long do I wait for the remaining six eggs to hatch before throwing them out.
