Chicken wire doesn't actually protect chickens from predators... Half inch or smaller hardware cloth is needed to keep them safe. The coop itself is a 4x8 (about 4' tall) building on stilts because that's roughly the minimum space that's healthy to keep in the winter if they get snowed out of their run. And I dont know where/when you've seen chicks for less than $1 per bird lately, last time I saw that was on broilers last year when the local feedstore accidentally ordered like 3000 instead of 300 and they were literally giving them away. Otherwise chicks are $4-5 each
