I have a 2 year old male canary, he was a wonderful singer. He molted in August and has not yet resumed his singing. It looks like he is starting to loose feathers again. He lives at my boutique, it is warm & bright. He gets fresh greens from the chef at the café next door every morning, fresh water, 2 types of seed and a clean bath everyday. He seems very healthy and active, but will not sing. Anyone have ay advice for how to get my little man to sing again?
