I'm sorry to hear of this with Penny. You appear to be describing a feather cyst which appear as in-grown feathers forming hard, yellow nodules on the skin of canaries. Those nodules contain trapped and curlng feathers and as the feathers continue to grow, the nodule grows. They may actually be benign neoplasms ("new growths") of the feather follicle. Treatment of individual cysts can be conservative, simply lancing and expressing the contents of the cyst. Recurrence is common unless surgical excision of the affected follicle is performed. Cysts on the wings may not be amenable to surgery without partial wing amputation and so conservative therapy may be warranted so long as you're aware of the probability of an ongoing problem. An avian vet (please see here: can advise concerning the best approach to Penney.
