I (finally) got chicks today! They are day old buff orpingtons-there are two of them. Due to hatch tomorrow are 5 more RIR's. Currently they are sleeping in the brooder, and have been since they got home. I briefly dipped each beak in water to be sure they had something to drink, and the food is out as well, but they have not eaten anything. Should I be worried that they haven't eaten in 3 hours? There was food with them at the feed store, so maybe they are just full? Thank you in advance
