Anyone know the behavior of finches when they have layed eggs? I can see about 3 in there nest(I only look quickly when the parents aren't in there). I have noticed that they don't sit for very long on the eggs. I mean the dad or mom sits on them for a short time, then comes away from the nest and flies around the cage and "plays"?(not breeding,just chasing each other) with the other...then goes back to the nest and does this all day. Should they be sitting on the nest a lot more than they are?
