locking down eggs 2 days early.. anyone done it?

[birdbrain5]

i am going to set some eggs today, i got a bit off schedule so if i do im going to have to lock them down 2 days early so they go in to hatch with my guineas and whatnot. i have put chicken eggs in lockdown one day early and it didnt seem to make much difference, but im wondering if 2 days is going to be alright? if i am able i would give them another turn but i know those guineas will be hatching right away so i probably wont get the opotunity to open my bator to turn them again. anyone think this is going to be a problem??

I've not got any personal experience but I have heard that there's very little variance in hatch rates if you stop turning 7 days before hatch! I should imagine those extra two days will make very little difference.
