I have 9 finshes, including a pair of Lady Goldians. They sat and sat in the nest. This morning one egg was missing, well the baby chick was still alive on the floor of the cage. I put him back. I am thrilled having my first finch, however, if they do it again, I will have to give the nest to another set of parents to adopt. The chick is naked, and 1 inch long.
