We have 8 chickens.. 5 weeks old or so. One inparticular is very friendly.. comes right over to us, jumps up on our hands, sits on my shoulder or lap and loves to be patted. She's a Buff Orpington and her name is Brownie.. Tonight we went to the mall with our kids so they could play in the big farmyard playground there and get a DQ ice cream.. We left the chickens in the run since it was 'secure'.. Well, when we got home I went to bring the chickens in for the night and there were only 7 of them there... The run is only about 8x12 so it was pretty easy to look in the corners for the missing bird.. Brownie ~ It was pretty dark but it was also pretty obvious she wasn't there... I couldn't imagine how a cat or something else could have possible got her.. then, I started looking more closely... looking... higher... and there, about 6 and a half feet off the ground... in the corner directly above where all the other birds were sleeping.... sat, Brownie. Lesson learned.. Never underestimate how well they can fly at this young age.. I've NEVER seen them pop off the ground more than a couple feet to get up on the stump we have in there.. I had no idea she could get that far up.
