We have 23 chicks 19 for sure females 4 straight runs so potentially 23 hens...we have the space to build 23 boxes but is that necessary or even good? A neighbor has 43 chickens (2 roosters) and only 5 nesting boxes bc she said many of her hens have slowed on laying (old age) and they will sleep in boxes with is "gross" (I'm guessing bc they poop in the nesting box?) our other neighbor has only 1 nest box for her 8 hens (but only 3 lay regularly) but I've read different things from 1 box per 2 hens to 1 box per 5 hens. Maybe if you only have 5 hens 1-2 boxes is okay but i don't want my laying hens holding in eggs waiting all day for a turn to sit. What is recommended for a flock our size?
