Canaries I have bred in years past have laid four or five eggs per clutch. They don't produce crop milk but female regurgitates what she has eaten to the chicks, I will provide vegetables, seed, pellets and hard-boiled egg for a wide variety of nutrition to help them grow when the time comes. Once eggs are laid the female will not get off the nest for 2 weeks except to poop and will rely on the male to bring her food - she begs like a chick to ask him to feed her and it is very cute. The male normally weans the babies and takes over care once they leave the nest.
Hoping, of course, they do have chicks! I got Mozart in December and Lyric this month. It has now been 3 seasons since I had canary babies and I am really wanting some more little peeps! For the past two years I tried breeding another male I have, who for the life of him can not figure out how to mate the hen (got on her backwards a lot...) and so only ever produced clear eggs. I have since given the female he was with to a friend as she was really pretty and I wanted her to breed for someone. That male was going to be a single for now but a few weeks ago I rescued another girl who was badly beaten up by others at a shop, and the two of them are getting along as just friends - she is not interested in him romantically but he is good natured and is not being pushy. That male is named Milo, and he's the most lovely shade of orange so it is such a shame he probably will never have chicks. The new rescue girl is pale yellow with a crest on her head. They'd make gorgeous babies if ever they got to that point and he got his act together.
