In our town the code reads "domestic fowl running loose" is a nuisance. So there you go...I think you will be fine.
I would not call and ask, better to ask for forgiveness, then beg for permission!
My daughter just brought CrackerJack in, she has the same but a wee bit worse. Not much else you can do. I do not use heat or lamps because I want the birds to be acclimated. I do apply Vaseline.
I am ordering the "All pullet rainbow pack" from Meyer. The bulk order of chics (25) keeps the price lower. I am in Lake County, Illinois. Price per chic is $3.00 each. Pick of the litter, I only want to raise five. I want to place the order this week, let me know how many you might be...
Protect from the wind, and have good ventilation. Also, have some petrol jelly for the combs. I remember one night it was -10 out, and in the coop it was 10 degrees, no light, no heat, no nothing! This was a 4x4 coop.
Good luck and have fun!
I would not buy it. Lay out some sticks or something to actually see those dimensions....too small. Look at your local home improvement store and see what they have as far as kids playhouses.
