So, I had read a few times that hens will "share" nesting boxes and you don't need the same amount of boxes as birds. We have 6 girls, all age 21 weeks. Only one has been laying (first egg last Thursday) and the other ones don't really look like they are even ready. The girl who is paying rent looks like she takes up all the space in the box that she has chosen. It doesn't look to me like theres enough room to share with others. How many nesting boxes should I really have made???
