My six mo old red sex link has been laying these sandpaper eggs for seven days in a row. I have done some research but can't figure out what is going on. I read that it could be taking longer to go through her system and more calcium is attaching to the eggs but she is laying everyday at around the same time so I don't think that's the reason. I don't think it has to do with her food. She has access to clean water and food. Are these okay to eat?
