Thank you for the info. I have 6- 1week old bitties. Judging by their wings feathers , I have possibly 4 hens and 2 roosters but only god knows for sure. Lol I hope to have 15-20 hens one day with a couple of roosters in separate coops. So I could start 1-2 boxes and add as I need too. Thank you so much.
Good idea to start with 1-2, as you say, you can add more later as your flock grows.
