I have two 10 week old Gold Laced Wyandotte chicks. "Sage" was very sick at about three weeks old (to the point of not standing up) but with a lot of help recovered. Ever since she has had such little growth, her feathers have hardly grown and she is tiny. Topaz, the other one is double in size and has lots of feathers. Could Sage be stunted? Will she always be smaller?
