Dont worry about samonella, unless you dont wash your hands, which you should be esp if you go to the feed store or handle chicks from else where you dont want to bring anything home to them. I have had chicks for awhile and hatch all the time and have never been sick from my chicks! give lots of treat, those that are good for them, I give left over veggies, and when I am pullingup things from the garden like carrots etc give them the tops, lettuce spinach etc. they will soon learn you bring the food and the treats and will come running but be prepared they will eventually want to sit in your lap!
