I havery the little giant foam, still air incubator with optional turner from tsc. Hatching quail, ducks, standard and bantam eggs. All seem to be hatching 7-10 days later than they should be. Checked the temp in bator with 2 completely different thermometers, I keep it between 99-100° f. Entire hatches are late, so not cold spots. I collect eggs daily. Store them pointy end down for a week tops, to allow them to warm to room temp. I only add eggs on the days I candle. Also having issues with late chick death in hatcher. Hatcher is little giant also, but no turner. I very carefully move eggs 3 days before supposed hatch. Hatcher is kept as close to the same condition as incubator as possible. Most are not even piping into the air cell at death. I've opened a few and I don't see any issues. By all accounts, they should be hatching, not dying. Please help?
