LOL.... I can just picture your description of their escape attempts.
The girls are full of beans usually, and the boys seem laid back for the most part, but they have their moments. It always seems in the morning when I let them out, which is not every morning, they come out and fly about like a bunch of knuckle heads......then settle in and begin calling for their food.
The parent stock I had were flighty, almost every night I was pulling them down and putting them in their cages, actually all my turkeys were terrible for this. I have eliminated the ability for them to cause any havoc, I started to lock them up every night an hour before dark, otherwise they would be up on top of their pens or the fence or chicken coop, I have gotten into the routine of putting them away when they are out, that I forget the fun they like to have come dusk.
Hopefully they will settle in and become less adventurous, and are going to behave for you... Perhaps they were just getting a better vantage point of their new home? LOL
I can see them wanting to get up high as they can, as the roost in the enclosure they were raised in is about 6 feet off the ground. Total height of their pen is a tad over 8 feet.
With the parent stock in fall last year, they would jump up on one fence then jump up onto another then leap for dear life to get onto our 8 foot tall pheasant pens, they would cling on wings a flapping just a hollering and climb up and then pull themselves over the top... They even taught one of my BR rooster, paleface their sneaky tactics.
Sometimes they would try to roost on our camper as well.
On top of the pheasant pens... Silly Birds.
