Would a thermostatically heated rubbery-plastic TSC dog bowl be a decent solution for frozen water (I have 6 chickens).  Is there a way to rig it up to keep them from falling in/roosting on it?  Any ideas would be really helpful.  The 3 gal heated waterer seems excessive for our little flock.  this is about a gallon, and only $24.
