CONGRATS Sharon

. You did great. I know how you felt once those chicks went airborne.
It's not over until they leave tho. Many will stay for a few days up to a few weeks, as the chicks learn to catch food, fly better & land. Keep an eye on any grounded chicks. Sometimes they can't find food & parents won't feed them or they get soaked in a rain storm, end up on the ground & need rescued (approach slowly, toss a towel over them or use a butterfly net-just posting this in case you have an emergency & no one is here to help you at the time) & dried off (wrap in paper towels for a few minutes & put back in the nest).
Then one day the parents decide it time for them to head to a main roost & off they go. Many times they will leave early in the morning. They'll fly around a few times, calling as if to say goodbye until next year & off they go. This is the worst time for landlords. The lack of sound is deafening. You finally realize just how much sound they really make. Leave your houses up into late October, as you could get visitors migrating. Then clean them out & winterize.
Drag out the photos you took & drool over them until spring. Now you have time to get all those projects done you let go, because you spent all your time watching the Martins, LOL.
Again Congrats Sharon.
