I currently have 5, 5 day old chicks brooding in what I thought was a sufficiently deep and long enough plastic tote. I have pine shavings on the floor and a heat lamp clamped to the side. Well today, my light Brahma, who is quite a bit bigger than the rest, flew out of the brooder. I can’t put a lid with holes in it on the brooder box now because of the heat lamp attached to the side of the box. I have ordered a Brinsea Eco Glow to replace the clamped-on light. Once I have that, do you see any problem with keeping the tote’s plastic lid - with many holes drilled into it - on top of the brooder so that the babies don’t fly out?
