i'm getting around 30-35 chicks and i've never had that many chicks i only had like 20 but it was a small brooder and now that i'm getting 30-35 i need a bigger brooder i'm trying to make one outside because i don't have space for a brooder inside and specially for 30-35 chicks. Can someone show me how to make a brooder for 30 chicks? outside the house?
