I have sebright babies that hatched yesterday and today. I will be moving them to their brooder later tonight. Is a 18 gallon rubber maid tub okay? I usually brood them for a couple days in a cardboard box, but I do not have one. I put some hay on the bottom and have a heat lamp above. I just set up it with a thermometer to see what temp. it gets too. What do you use for bedding when they are in the brooder?
