Are there any special ways to pet chicks that they just love? (Like dogs getting scratched behind their ears or belly rubs) wondering if there's any spot a little chick just loves. We are working on getting ours comfortable with being held and petted. They still are a bit skittish at one and two weeks but not terribly so. I like holding them just over the ground before setting them down and letting them "roost" on my hand for a few seconds. Any other good tricks to making them comfortable and social?
