This can be the start of a very lucrative enterprise, producing approximately 48 chickens a month in a very limited space. Put approximately 48 chicks (day old) from a hatchery or incubator into the brooder for warmth, feed, and water. After four weeks, move 24 birds into each grow off pen and put 48 new chicks in the brooder. That's 96 birds kept comfortably in less than 11 square ft. 49 inches tall. Includes one brooder with 2 blue pilot bulbs, two expanded grow off pens, brooder base, and casters.
