The canary chicks no longer use the nest at all.  I cleaned the nest out today and provided new nesting material, and now Momma is happily working on lining a new nest.    Tonight there is one chick sleeping on the swing, one sleeping on a perch. and the youngest is sleeping in the seed bowl and twittering to himself.   Daddy is exhausted from running all over the cage feeding three demanding chicks.  There is a buffet of food appropriate for a baby bird, and they watch with great interest as their parents eat, but the chicks don't quite get the idea of feeding themselves.
