Hi, So we just got 14 chicks delivered 1 week ago. They grow bigger by the day and at first were very tolerable of human contact and did not mind when we would come into their stall. Now they are very tentative and will run away when we go in to feed the etc. Hate when we try to pick them up. Is there a way to tame them/socialize them so that they enjoy human contact and are not so dubious of our presence?
