Jumping off the deck?

My hen when to the deck and jumped to the high table she looked jump and looking at the roof and I'm wonder why she did that

For the same reason that 'the chicken crossed the road'.

Hen's like to get up high. I have one that would jump on one of the outside perch's and then from there to the roof of the coop. This is an 8ft coop with a peaked roof that goes up about 12ft. She likes to go to the top and when the other hens aren't looking she will dive bomb them. I didn't have a problem with it until she started leaving the run at which point I had to clip her wings. With hens it's definitely the higher the better in their mind.
