New coop-how to prepare for chooks

I wouldn't go to a poultry fair until you are far more experienced, many people have bought young cockerels after being told they were pullets and also sometimes you can bring home birds with illnesses. Try and chat to local chicken keepers and see who they recommend or visit several breeders (best time to go is before your coup is built - this way it stops you buying the first ones you see) and check out what they have, the conditions they are kept in and the health of the birds in stock. Do not be put off with some that look thread bare they could be moulting or a cockerels favourite girl.
As for the coup make sure if it is wooden that it has been treated with a preservative you don't want the wood to rot in the first winter, follow Hillfooters advice and paint the inside with a diatom slurry and then go shopping for birds 
Good luck xx
