I have a question about finch eggs. I was told that if a male and female finch breed and lay eggs you can boil the eggs and place them back in the cage until the finches get tired of them. I do have concerns though? 1. Do the eggs have a heart beat on day 1 of being laid? 2. Does this distress the parents in a substantial way, is it the same with chickens? Or do the parents really just not get distressed about it?
