Well, they should be turned... but if you cant, ya cant.... I feel quite sure you will still have some hatch. May not be a good hatch, or as good as it could have been anyway. I have never known anyone that went that long with out turning so experience in this situation, I have none... All I have is opinion, I think it will "dampen" your hatch but not drown it... You can only do what you can do. Let us know how it comes out. Bill
