Someone told  me that this is a Texas Rat Snake. Whatever it is, he has eaten a prcelain egg.  Some varieties of chicken snakes will die when they eat a porcelain or glass egg. This snake easily regurgitated the egg three times. Also the real eggs are broken and the shell is expelled in a wad. After eating a half dozen eggs, the snake looks pretty full. The last two snakes were after my Corturnix quail and killed three.They usuallly are trapped after they eat because they can't get back out through the same hole they came in.
