We have used old refrigerated box from the back of a tractor trailor... you will need to add some windows.. we have those spinny vent fans on the top of the coop. Our chickens are doing just fine... we are using a bigger one for our second coop. The metal seems to attract the heat.. so good ventilation is key... Rustoeum paint is our best friend!!!
Here is picture of ours... my boyfriend even got the lights to work ... they have a solar sensor and come on at night
Good luck with yours... great find
