Hehe, this is actually pretty common for first time chicken parents - I even felt a little freaked out when I first noticed my first lot of day olds with gigantic full crops one evening! They'd stuffed themselves absolutely full and were snuggling down to sleep, so they probably didn't appreciate my concerned handling and prodding, waking them up But oh well, it's better to be safe than sorry and reassurance is always nice

Also, when you end up taking them outside for the first time, don't be freaked out when they start throwing themselves at the ground, kicking their legs around and flinging dirt everywhere with their wings and feathers all puffed up - They look like they're having some sort of fit but they're just dustbathing, hehe. I've seen a lot of concerned new chick parents frantically worried about that too, so I figured I'd give you a heads up just in case

Chickens are seriously funny and interesting animals, full of silly quirks and funny habits. Enjoy your babies while they're young and fluffy!
