Hi everyone, We'll be getting about 20 chicks this week and will need to pull a coop together pretty quickly. We'll need space for about 15 adults. We'd like to stay in the $200-300 range. Anyone have any ideas or point us to where to look? I received free plans for a nice coop, but it's way out of our budget. Also, at how many weeks should I expect to have to transfer the hens to the coop? We have mostly Rhode Island Reds, with a handful of Black Broilers. We're in North Texas if that helps with design for weather. Thanks!
