Hello our family is brand-new at chicken raising. We bought 8 chicks at tractor supply went back two days later to buy the coop and then bought six more chicks. I am a bit nervous for the amount of chickens we have and the size coop we bought. The coop we purchased was an extra large coop, stating on the box that it holds up to 18 standard size chickens. So my husband thought if we had 14 we should be fine. I heard you need 4 ft.² square feet per chicken. I am doing the math and it doesn't make sense to me. I am confused because the coop holds up to 18 chickens and we have 15 which would be okay, but I've also heard that you need 4 ft.² for every chicken ,so why would the company stateon the box that it holds this many chickens when you need 4 ft.²?? Help!!
