My Turner is still noisy, but did seem to quiet down some after doing an eight hour dry run. It was just as loud with the metal screen in or out. Must just be the nature of the beast?!? If I manage to get a hatch I hope the chicks aren't deaf!! Lol
I just plugged a brand new out of the box 4250 in and am hearing loud noises out of the egg Turner! I can't believe it's normal... Sounds like a tiny helicopter is landing in there!
