ARE LIZARDS Predator WILL IS HEART MY CHCIKENS BECAUSE IS SUMMER AND ITS HOT THE LIZARDS GET OUT AND I AM SCARED IF IT WILL HEART MY CHICKENS PLEASE HELP I AM WAITING FOR YOUR ANSWER!
Ummm, lizards don't have teeth. They have sharp jaws, rather like chickens have sharp beaks.
Iguanas are large lizards, but as adults are vegetarian, chuckawalla and gila monsters are large, and would eat a chicken if they got hold of one. Not sure about the chuck's, but gila monsters are REALLY slow, so as long as they don't catch the chicken in a bite...
As for a lizard the size of a finger, it is too small to eat even a bantam chick. Consider the size of the lizard's mouth, and its normal food size. Probably small crickets and possibly meal worms.
