I am hatching my first eggs (testing with some mixed breeds). My new incubator holds up to 82 eggs...right now I just have 12 in it. My question is, can you add other eggs in once you started? In other words, lets say on day 5 of the first 12 I get another dozen. Is it ok to add them into the incubator and just mark when you put them in? I don't have a hatcher, but I do have a second shelf in my incubator that isn't being used currently. If I did have a hatcher, I am assuming you could do this without any problem.....but I know what happens when you assume. Interested in your feedback.
