I'm getting my first chicks at the end of February and I'm almost ready. I have a 5' sq box, some chick grit, a little homemade feeder, some electrolytes, a waterer, and heat lamp. Just need to order their food. Right now I have an old towel folded in the bottom of the brooder. I know they need wood chips for bedding but do you use that from the start or is an old towel Good for the first week or two. After the first week or two, my chicks will be relocating to a large, old dog crate set up out on the screen porch with wood shavings and their heat lamp ect. I just need to know when to start using wood shavings for bedding.
