So we are getting ready to try out our first incubation. We have 10 eggs from our own chickens and about another 10-12 shipped eggs coming in the mail. We are getting about 3 eggs a day right now from our hens, so depending on if I start tonight or later, we could have 3-6 additional of our own eggs to add in there. How many do you think we should try putting in for our first try. We aren't looking to end up with 20+ chickens, but I've also heard that shipped eggs tend to go about 50% and I have no idea how well our own eggs will hatch. Would you just put them all in and see what happens? Do you think expecting an overall around 50% is realistic for our first try? Thanks!!
