When mine used to free range the returned to the pen but getting them to go into the aviary was another thing entirely.Mine have to be herded into their pen in the evening but it has gotten much quicker if takes one minute now. From what i hear they are like geese in that they don't return to a coop. I have heard the occasional person saying theirs do but you can probably assume they won't. I just have a big secure pen and a dog kennel. It's 15 x 40 ft. I have a fenced yard I let them into during the day only when I am here to check on them. They are next to the geese who let me know if anything is amiss.
