Many years ago we tragically lost our beautiful rook fledgling Blacky. He came to us after a nest fall following a storm. Blacky also suffered of splay legs, muscle atrophy and suboptimal plumage development, presumably due to a nutritional deficiency. At arrival Blacky was not able to stand on his feet, nor was he able to perch properly. We designed and applied a custom made brace to correct the malposition and to counteract the subluxation tendency. At the same time the brace did allow Blacky to exercise sufficiently to built up his muscle strength. We did combine this treatment approach with regular physiotherapy and an optimised diet.
