Had a new Large Egg for a week. Just noticed the bottom vent will not slide open all the way it hits up against one of the legs on the nest, the men who delivered it apparently didn't align this correctly. Read all the instructions and looked at the bands/handler, etc. I can't figure out which parts I actually have to loosen to rotate the bottom part of the egg about 4 inches but keep everything else aligned. Any help appreciated I am not too handy with this kind of stuff.
