I'm getting a batch of 30 chickens in July and would like to put them in a brooder box in my barn. I have a "duck tractor" that is 4 x 10 wrapped in hardware cloth that will work for the brooder and an old animal stall in the barn to park it in. (I'd rather have them in the house to keep a closer eye on them but husband says NO WAY.) Here's the problem: I'm worried about our many many raccoons wrecking the heat lamp and rushing the chicks to one end/corner where they were get squished. Any ideas on how to keep the chicks from getting spooked by the raccoons rushing the wire at night while still allowing ventilation / heat? They shouldn't be able to get through the hardware cloth but I've had chickens/ducks die by getting so stressed at having a predator so close.
