Hey there, I was just getting ready to order one. Started my "freeezer-bator" some months ago....never finished. Got the heating element sitting right here. Needed to order a fan. Let me know. PM me if you would like.OK for anybody looking to build an incubator or install a fan in a still air LISTEN UP ! ! ! DO NOT spend too much on a fan! I just scrapped a Wolfe tanning bed. In it was 8 yes eight nice 115 VAC fans. PERFECT for bators. They are about 4" square and 1 1/2" +/- thick. They will be cheap to chicken buddies.
