It seems the little things just grow so fast their legs suffer and they can have leg issue so it's best to start them off right away using Nutritional yeast then if you begin to notice even the slightest problem start the B Complex. Nutritional yeast is easy to use just sprinkle over feed 1 Tab per cup of feed. Hopefully yours won't have any problems but it's always best to be ready just in case.
