Yes I have done 28-30 in there. 30 is tight. Lol. And @Iluveggers has done it many times.Thank you! I remember reading multiple posts in this thread of folks hatching more than 22 eggs, just couldn't remember how they were stacking them
Before I started doing it that way I used an egg carton and cut out individual cups, cut a hole in the bottom so air could circulate. Then iluveggers tried the other way and it was much easier!!!
