Hi, I'm a total newbie at this and have some questions. I just got an incubator (and of course am very excited.). Before I purchase eggs I thought I would try hatching my own first so I know what I am doing. My incubator will hold 24 eggs, but if I am just trying to see if it works, how many eggs should I put in? I'm not sure I want to hatch too many of my own, as my rooster is a different breed from my hens. Also, how long should a hen be laying before you try to hatch her eggs? Are pullet eggs too small? I have two hens laying since the beginning of the month and their eggs are medium compared to store bought eggs, and I have two younger birds I am waiting for them to start laying. I am tempted to wait for the younger hens to start so I can include their eggs or should I just go ahead with the eggs I am getting now or should I wait a bit and see if the eggs get larger? I had thought of trying with four eggs or is that too few? My only worry would be that I hatch a singleton, I would rather have a few for company. Thanks for any info.
