Crowing
My finches have very strong maternal instincts. I normally take their eggs and replace them with fakes or I'd be overrun with chicks. I have a pair and their grown son and daughter all together. The momma finch seems ecstatic her plastic eggs hatched after like three months, no matter how wrong her babies this time look. Fingers crossed they will continue to foster, at least until the canaries are a little older and louder and I can try them with their mom again and see if she will feed them then (as being raised by their own species is going to be better for them learning to be canaries.)
