Yellow canaries are very cute and popular. When they are infants, they look like little chickens! If birdies are happy, they always sing. Only male sings good song. Put either a pair of cock & hen or a pair of cock together in one cage, they'll probably don't sing. The former are busy on 'dating' while the later are normally fighting for their boundary!
Birdies enjoy bathing. Give them a dish of water, they'll bath themselves in a sunny good weather. Explore them to sunshine (not direct sun) with fresh air, that's easy to see (hear) how enjoy they are! No matter wire cage or bamboo cage you're using, make sure it is clean and has enough space for them to do exercises. Fatty bird don't sing! =D
