Bertha started out sitting on 11 eggs. Then one day, 3 were pushed out of the nest and she had 8. May 28 was day 21 and nothing hatched. I wasn't sure she had not had other hens add to the clutch, so I left her alone. Yesterday, day 32, all the bedding was pushed up against the back wall of the nest box and 3 eggs were at the front. I just happened to go in when she was out, but she rushed right in and sat on them. Now, day 33 and still nothing. She's still sitting, dashing out for food, water, and a poo. How long do I give her before cleaning it all out and calling it quits? I was thinking Thursday (day 35). I am really wanting a hatch. Thanks.
