It's only 5' tall, so yeah, they could have flown over.![]()
Havoc's right they could have easily flown over. My kelso pullets from this season can easily be found 30+ft up in the trees, I've seen em fly from our porch to the back side of barn which is pretty far aswell and they are pleasantly plump from being free range birds.
If ya got the room I'd keep em.
