I love having good cover for my birds. There are several giant ligustrum in one area that they love hanging out in/under. By giant, I mean they have reached a good 15-20ft tall, and all run together in to one bank that is probably 20x50. There is also a pair of mature cedars that are limbed all the way to the ground, but they prefer the denser cover of ligustrum most of the time.
As far as planting for more cover... I like vines and large roses. As long as your put some pavers over the root base the chooks digging/dusting isn't a problem.

. I don't know if we have enough time for roots to establish before winter hits now. When transplanted they look half dead their first year. Second year they leaf out and are a small bush as expected. Third year they are hitting their stride. By 5th year you have a 5 foot tall and 4-6 foot diameter plant that can have portions removed and propagated to another spot in the garden. Maybe even sooner. They'll spread by root runners. I trim them very lightly. As I like them tall. But they will take pruning as low as a foot to foot and a half.
