I have a week-old hatchery d'Uccle that seemed a little bit "down" when I fed this morning. It just acted tiered and for the most part, kept one eye closed. To make sure it was staying hydrated, I held it to the water and it drank twice. This evening, it keeps doing a motion that looks like a yawn. Also, both of its eyes are closed now.. What can I do!? This chick is very special to me Thanks!
