I had similar problems with my old lgs at first. After a few bad hatches I got it figured out. I had to watch the humidity more closely. I also had to clean and sterilize the bator more thoroughly. It was frustrating at first but then I got it figured out and it became quite easy.I also set 24 eggs on the 26th! In the past I suck at hatching my own eggs, but I just bought a egg turner for my little gaint incubator and I hope it makes a differance cause in the past 2 times I tried to hatch my own chicks it was a fail without the turner. Hope that the turnr helps alot
These are among the first setting in my new sportsman 1502 I also have 100 eggs from my own chickens due next, about 40 barred rocks, 12 guineas, and 6 mf duccles.
