I didn't even know about hatch-a-longs until today. We're also on our first use of the incubator and our very first time trying to hatch. Set 23 eggs so far - two rounds. First batch should hatch the week before Easter and the second the weekend of Easter. I candled the first batch at 1 week and had good movement in 9 of 11. At 10 days, in 10 of 11, so I pulled the stagnant one to prevent a blow up. Tonight will be candling the second batch since we're at 7ish days. And I'll be checking progress on the first batch since they are at about 14 days. So excited to hatch our own. They are mixed breed bantams. Their parents were the offspring of a varied flock of purebred free-range bantams, so they have some very fun mixed characteristics and lay a beaufitul pinkish egg. So excited to see who hatches!
