I know they are still young layers but it is almost like they are getting dropped or stepped on. Now I put cut straw in the nesting box but they always push it aside when they lay making a dent which is fine but it exposes the wood on the bottom. I don't know if that is the problem or if it is just a calcium issue. Sometimes it is broken further but those are usually in the main coop area and not in the nesting box. Any ideas?
