I set about 6 dzn eggs. It was over the course of 3 days and some didn't make it to the second candling, more didn't make it to the day 18 candling. I think we are done with the hatch. I have about 30 chicks in the brooder and 12 or so in the incubator for one last nite. I really don't expect the last 12 to hatch. All were shipped eggs. The best hatch was with a semi local breeder, about 450 miles away. I got 75% of shipped eggs of hers hatched. The rest are much less. I have 3 dozn to hatch in two weeks and another 3 dzn eggs the following week. Its been successful as far as I'm concerned!! I really hope the new sets do better, but I can't complain with what I've gotten.Just had to share that with someone!! My lemon blue cochin chicks are gorgeous!!
