We've used a Brinsea 20 to hatch Turkey, Chicken, Duck, Pheasant and Quail eggs for the last few years, with pretty good results.
I always try to put them in with the pointed ends down (you get more in that way) and have never had any problems with them trying to hatch out of the pointed end.
The Brinsea kind of rolls/rocks from side to side so they eggs are moved rather that turned.
