I have 3 BR pullets that are almost 20 weeks old and 1 WR hen. Our hen always lays in the nest box. She didn't even stop when we modified her coop, added to it and moved the nest boxes to another location in the coop. This morning I found a broken egg underneath where the hen roosts, the shell had been played with, but nothing was eaten (that I could tell). At first I thought she might have laid while roosting, but I think it is more likely it is a pullet egg...The shell seemed a bit thinner than the hen's normal eggs. I didn't do anything to "train" the pullets to the nest boxes. They have been living with the hen since June and have seen her lay eggs in the nest boxes and as far as I can tell, they never bothered her eggs. So what do you think? Am I going to have an egg eating issue or do you think once the shells get a bit thicker, they will leave them alone? It's just such a let down to wait so long for that first egg from chicks you raised, only to find it broken!! Thank you!!
