I have done poultry presentations the last couple of years in some of our local grade schools for their "Environmental Awareness" day. Baby chicks and how to properly brood them is always a big hit with the kids. After the presentation, with the permission of the teachers, I explain how to hold and handle the chicks and then let them do it for a few minutes. Large fowl work better for this, as bantams are more delicate and can't handle the stress as well. You need to know the age range of the attendees and gear the amount of detail according to their comprehension level. In my case, it is usually one or two grade levels at a time, then they file out and another group comes in, so I adapt as best I can to what I think they can take in.
