Great picture!

So, you estimate that they need only three weeks to be able to fledge?

Thanks tom123.

I received a reply post from ctnchpr who estimated them flying away at around 21 days...give or take a few days.
You can see the pic when they were 8-9 days old on the link below.

I also have pics from when they were just two tiny eggs and also 1-2 days after hatching. Precious little things. Just so happy they did not come to any harm from predators.

Here is a link that might be useful: 8 - 9 Days Old

They are so cute!
