If basic power tools aren't a problem I'd consider a prefab shed. They are easy enough to add roosts to. Extra ventilation too. Likely cheaper(also more fun in my opinion).My impression of the TSC kits was also negative. I am working with a carpenter who says for $1500 he can make a coop 5 feet x 8 feet with a small feed room leaving the house for chickens 5 x 5 which would house 12 chickens. Run could be made 6 Feet x 8 feet long which would be 4 square foot of run space per chicken along with the 2 square foot inside for a total of 6 sq ft per chicken. Does that sound correct for 12 chickens and does that price sound resonable?
