We have a couple of skinks outside out house that have recently taken an interest in our newest baby and have tried to attack her on several occasions. Are skinks a predator of baby chicks and do chickens come with a natural instinct to detect predators? My two babies did not seem phased at all by the lizard even though the lizard was big enough to possibly eat one of them. I think I was more scared than my two babies and it puzzled me as to why they wouldn't react. Do chickens have to be taught what is friend and foe in the outside world?
