I have had one "hold out" with my 4 21 weekers. Yesterday got 3 eggs and the 4th pullet yelled victory for each of them and spent most of the day herself in the next box, but didn't give up an egg. Finally came out of the nest box around 4 PM and preened and scratched like normal. This morning, there was one egg when I let them out. I witnessed another go into the nest box and she laid an egg about 20 minutes later. The loud mouth from yesterday was very quiet but acting normal today. I noticed something on the floor that looked slightly like an egg. Yep, it was a soft shell egg. I couldn't get to it easily so grabbed the dog pooper scooper. Managed to get it but it broke and the yolk broke too. I managed to get the soft shell but the vultures attacked. It was like someone yelled to them that there was food. They found every drop of egg and yolk. Do I have to worry about an egg eater now?? They didn't touch it all day until I stupidly broke it.
