Is it Ok to do a batch of eggs in my Brinsea Octagon 20 out in the barn? I live in Oregon and temps are low to mid 80's daytime and down to about 59 at night. I know it's ideal to have a constant 70 ish degrees but wonder of anyone has tried it in a barn. My barn is well protected, a big horse stall with rubber mats, good air circulation but never breezy.
