I put some refrigerated eggs from my flock of just 1 rooster and 11 hens, total of 15 eggs, in the incubator. A Still-Air incubator. Wanted to put 15 to maybe at least get 1 or 2 chicks. I turned them twice a day, not at any consistent time. Put a little bit of water in those rings and the temp fluctuated between 95 and 104. I only candled 2 eggs on day 10 and they looked like something was in them, so I figured, hey there is my 2. Well on Easter 12 hatched and today the last 3 hatched. Today they were due. They all look healthy and no problems. Is that lucky or does this happen? If I do it again, will it or should it happen this way again? BTW, this was my very first hatch.
