Set about that many last year and had a pretty good hatch rate. The only thing I have done different this year is I put two little bantam eggs in one of those little kiddie incubators to see if they will hatch. When I was a kid we had three hatch in one of those. My daughter has tried for three years with this incubator and they would either not develop at all one year and the last two years, they would develop but not hatch or some would stop developing. The temp in there is perfect along with water, so we will see what happens here.
