My mom teaches Pre-K and does a chicken project every year still. Those kids love it! They have them in the incubator as eggs in the classroom until they hatch. Then she takes them home to raise and the kids get to take a field trip every few weeks to visit them.
Sandra, they are actually close to 2 weeks old now (we got them Sat. and they were around a week old then), so yes, they are starting to get their feathers. That is neat that your mom does a "chicken project" each year with her kiddos. I remember doing that in elementary school too.
Chelle, wow 20,000 chickens!!! Yeah, I might be a little chickened out then too. We are definitely going to get more next spring if it goes well with these ones. Ideally we will end up with about 25-30 - that's how many we need to keep up with our "egg intake." Yep, we eat an insane amount of eggs!
