Chicken Tender
Personally, I have a homemade one from a styrofoam ice chest I have one adjustable one on top that can be closed or as big as 2 inches by 3 inches, on the top, and one lower one on the right side that is about 1 inch by 2 inches and a couple ink pen size holes poked on the front. They get good ventilation and temp and humidity stay fine once I get them balanced.
Okay I like the making it bigger smaller idea to adjust that sounds awesome!! My cooler is hard plastic Coleman. Does this make a difference?
