I bought an Ecoglow 20 brooder and I'm wondering how it works. It doesn't seem to have any thermostat to adjust the temperature. Can you use it in a colder space, like a garage? (we can still get temps well below 0 and snow ) Can I put it in a somewhat closed in space like a tub with a lid on it with vents. I will be hatching eggs at a nursing home and they have a cat. If you have any ideas for a brooder box that would be easy to see into and take chicks out of please let me know. These other ladies are really getting into this. It is a 4-H project. They have already announced it on the radio and paper - small town. I was thinking of kids and old ladies and old men. I'm starting to stress over this. What did I do!
