Hatching two different ages of chicken eggs at the same time?

    So I had 10 eggs going well (due for lock down in 2 days) when a friend gave me a dozen fertile eggs 4 days ago.

    As I had room in the 'bator I put them in.

    Is there a trick to hatching different ages of eggs in the same 'bator?

    I have them in an egg turner so could take out a few of the egg holders and put in a wire tray for them to hatch in but what effect with the higher humidity have on the developing eggs?

    Any help on this one would be great, if it can be done it would make successive hatchings easier as I could do them weekly.

    The higher humidity during hatching isn't a big concern for the developing eggs since it is only for a couple days. It is more of an average humidity throughout that constitutes toe proper weight loss.
    More of an issue is the fact that you don't want turning the last couple days so you either turn off the turner the last 3 days of the first batch or better yet, pull the turner and lay all the eggs flat. As the chicks hatch, they'll play soccer with the unhatched eggs and may have the effect of turning them.
