We started with a 12x12 shed we already had and ran electricity to it, insulated the ceiling and walls, then put up paneling. Then we added 2 GQF Sportsman incubators and a sportsman hatcher. We have 2 BIG troughs that hold 50-100 chicks and then a couple smaller ones that hold small amounts of turkeys and ducks. We also have an air condtioner installed and a heater. Total light bill EVERY month: $450-$650. Total amount of chickens sold: between $5 and $100. We also built three brooder boxes that are 6ftx3ftx2ft that are up on 3ft legs that the chicks go into outside after they don't need lights anymore. Well one of them is wrapped up and has two lights in there in case I run out of room in the hatching house and the overflow goes in the heated brooder box. These are made of treated wood, chicken wire and galvanized tin= not cheap. Plus the cost of feed is running us at least $600 a month. Total invested to get started: Incubators $1800, paneling, lumber, insulation: $200, wire, conduit etc to run power: $450, heat lamps, waterers, feeders etc: $100, AC:$180, heater:$75, and light bill $450-$650. Not to mention the cost of keeping the big birds that lay the eggs, the sweat and tears.
