This is my 1st Brooder. It is for chicks aged 0 to 2.5 weeks, it lives in the dining room on the table.I made it out of scrap that I found around the place then just bought the heatlamp and fittings. It is around 700cm x 700cm x 350cm tall. At 2.5 weeks of age they then go out to the big brooder on the deck (under construction). Its huge, 1500cm x 900cm x 900cm tall.
