I have 5 chickens, 1 nest box. When constructing my coop after doing much reading, it seemed one nest box may be sufficient for 5 birds. They don't all lay every day. I live in a cold climate and read that the constant rotation of birds in the box may help keep the eggs from freezing. It sounds like others experience that their flock picks a favorite nest box and they don't use all the nest available anyway. My girls were slow to start laying and now they are approaching a year old and spring is coming and all five are laying with more regularity. This week I found my newest/youngest layer had made her own nest in some pine shavings and laid there instead of the box. I've found some oops eggs from new layers in odd places, but this was a very deliberately created nest. Now this may be because she doesn't quite get it yet, but I'm wondering if I may need another nest box? Too many girls trying to lay at the same time, or one of the girls higher in the pecking order dominating the box? How many nest boxes would you have for 5 layers?
