Is my brooder plate enough?

[CMH Ohio]

I just felt bad picturing 3 newborn chicks in a wire cage in the middle of a garage. Maybe if he posted a picture it wouldn't seem so cold. I'm in Wisconsin vs. Florida, so big difference there too!

If your broader is wire then a draft guard around would help. I use in my basement and they seem comfortable. I have only 3 bantam chicks with heat plate.
