I currently have 9 pullets that are laying an average of 7 eggs/day. I have 4 nesting boxes and I usually see 3 pullets using 3 of the 4 boxes every morning. But this has been so much fun that I'm receiving another 12 pullet chicks in a couple of weeks. I had thought perhaps I could get by with the 4 nesting boxes but now it looks like I'll need another 4 boxes. This will be using up more space in my 12'X12' coop ... I'm also planning to build new roosting area for the new chicks. I suppose it will just get a little more crowded in the coop than I would like but I don't see any other option. This is my 1st year as a chicken farmer ... I'm loving it ... but from earlier reading I had believed that there wasn't a need for so many nesting boxes ... however, I wouldn't want my ladies to need a place to lay their load and see a 'no vacancy' sign....lol
