WOW, & I thought our halk crazy... I dont think its age, Its just he way they are. I have pens 30 feet from my door and one of my babies came up missing ( no tops in the 1+ years I have had them ) So it was time to get some tops on.. we framed them out with wood and lowered them down on the top of there pens.... Next morning the halk was sitting on the frame watching there door, he could not get to them. As soon as I opened my door he took off. I have posted on here because in the last few weeks I have lost 3, 2 were killed by something that dug a hole under there fence, we have set traps & cought a oppussem & a fox.... WE re did all the pens so everything is framed in wood/fence 100%...... Now I did not get but 1 reply here, when I posted so I googled and found that this time of year is the worst for loss, The leaves have fallen off the trees to open up areas on the ground that were not seen just a month ago, the grass is dorment and lower then just cut grass, hay field grass is now laying & allows ground animals to see much more & further. I have seen a site were one owner talks about its a warning to a bad winter comming. For the halk issues, if they can not get them they will soon stop coming, they will move on to a feeding area. I have not seen our halk near the pens but I have seen him flying way above & he kept on flying.
Good luck, I hope he moves on soon & leaves you alone
