I wouldnt worry too much about temp as long as its nothing crazy hot like 80's or 90's. Its really hot here where I am currently and my house is roughly between 65 - 75°. Still get great hatches! Cooler temps are just ideal. But we have a hard time keeping the house cool in the summer heat.I run a fan at night . . . would it be ok if it wasn't pointed at the eggs? My room temperature doesn't fall below 68 because I run multiple heating elements 24/7. (I have a dubia colony and bearded dragon).
