I've gone from one egg layer to 5 in only 3 days! (two laying yesterday - 5 today). It feels great to see those lovely brown eggs in the nest boxes. I collected 4 at noon, heard the egg song half an hour later and went to coop. No one in the box, but believe the Dominique on the coop floor was the layer (she's been "squatting" for a week or so). When I took her egg into house, I noticed that although it was quite a bit larger than the other pullets who laid for the first time today, the small end of the egg had a dent/crack in it Well, we won't be eating that egg, but would like to prevent it happening again. Currently I have shavings in the boxes, although they seemed to have pushed a lot of them out of the box along with the plastic eggs that were there. Should I A. Keep replacing the shavings B. Try replacing shavings with hay or straw? C. Put foam type of mat on the bottom (Like the playmats for children)? Any suggestions from the more experienced chicken keepers would be greatly appreciated!
