Hi all, This is my first time raising baby chicks. I have a handful of Silkie chicks who are now 4 weeks old today (I have had them since they were a couple days old) I noticed a couple weeks ago that 1 of my silkies had limited, little motion in one wing. Now that they are growing, it is obvious that the wing has little to no range of motion. The wing is growing properly, growing all feathers, and is not "limp" or dragging. My question is, what do I do?? Thank you for your input!!
