First off, when they get there they are going to need a warm place to go, food and water. Make sure all this is ready to go before you chicks arrive. When they do get in, show them where the water is and where the food is. After that, leave them alone for the day. Let them get used to thier new home. The next day and many days after you need to check on them 3,4,5 times a day. When you do, talk to them. Every time I see them I say,"Hey chickie, chickie. Now when they hear that they know its me. Kind of like the Mama hens clucking to them. When you visit try to pick everyone of them up one at a time. Cup the chick in your hands so it can feel the warmth. When the chick settles try strocking it a bit, Kind of like Mama hens preening. Then put it down and go to the next untill everyone gets a turn. If you do this every day they will eventually come around. I got 2 little buggers that run up to me now ready for a little attention. The rest tolerate me. But there is 2 of the 16 that just dont like to be handled. I respect that. But those 2 will be the first to take a tiny mealworm from my hand. At 2 weeks old I introduced the little guys to the outside world and Meal worms. This really made them come around. When we are outside they are more communicable. And after they get thier little beaks on some meal worms,(AKA Chicken Crack) they really get friendly. When they are outside, Make sure its a warm day and they have some shelter from the wind and a sunny spot and a shady spot. If they start peeping loudly and consistantly, they need to go back to the heat lamp.
