We have increased our flock size and are increasing the run and coop space. Our original coop has 6 nesting boxes and roosting for 20 chickens. Our original run is 10' x 20'. The added run will be another 10' x 20'. The added coop space will be 3' x 10'. We lost over half our flock this time last year from predators, so I'm no longer comfortable letting them free range. I have a chicken tractor that I plan on using for planned breeding. We currently have 49 in our flock. 5 are mature birds, 44 are chicks ranging from 2 - 7 weeks. 6 chicks are going to my daughter, I will keep my original 5 and 23 of my pullets. The remaining chicks will go to auction. Do you all think I am providing enough space for 28 birds?
