My husband built a brooder box for our now 3 week old chicks. I've been out of town the entire time. The bedding wasn't kept up and now the wood at the bottom of the box is covered in poo. I have day old chicks I just got in today. My husband built a larger brooder for the 3 week old chicks and wants to move the day old chicks into the older brooder box. If I clean it out with bleach water... will it be sanitary enough? I thought I heard something somewhere about not reusing brooder boxes (or was that incubators?) for new chicks as they are susceptible to bacteria. Has anyone done what we are trying to do? I would REALLY appreciate any feedback! My husband says he can't put a new bottom on the old brooder box because he used nails... any ideas?
