I have 9 full size breed chicks to be delivered in a few weeks. The question is where to brood them: My first preference would be inside a small coop outdoors. The coop is 30 sqft, predator proof, with about 16 sqft of ventilation. The concern is the temps here in south east Texas are from 80 in the morning with high humidity to upper 90s in the afternoon. I could add a heat lamp on one side, however the temperature would vary a lot due to the air temp. It may get way too hot for them. Or, do you think they’d be okay without the lamp. Alternatively, I could keep them inside where it’s 75-77 all day in a 1.5 wide x 3 ft long cardboard box with a heat lamp on one side. I don’t prefer this route due to the heat lamp in the house by the cardboard and my kids won’t be able to leave it alone.
