I added five new chicks six months ago and apparently some of them have started laying. (We have a total of ten hens) for the last three days when I have gone to collect eggs I have found some eggs scattered and buried under pine shavings, cracked etc. I think the young girls are clearing out the laying boxes first and the whole coop is in upheaval. Will this behavior pass? Do I need to get extra boxes? We have three boxes. Thoughts?
