A New Jersey duck born with a lame left leg can now waddle around thanks to a specially tailored wheelchair. Merlin was adopted by a sanctuary in Annandale, New Jersey, in November but was immobile due to a birth defect in his leg. The sanctuary contacted Walkin’ Pets, a business that designs and fits disabled pets with nifty wheelchairs in Amherst, New Hampshire. Engineers worked to modify the company’s mini wheelchair model, usually used for cats and dogs, to help accommodate Merlin’s physique. Merlin was fitted with his new wheels earlier this month.
