I've had my little backyard flock for going on a week now and everyone seems happy and has been very well behaved (3 birds). I want to let them free range in the yard a bit. Any pointers on introducing them to this for the first time? I'll probably only let them out for an hour. When it's time to go back in what's the best way to get them back into the run without getting them too stressed out? I have handled the birds and they're fine once caught, but they don't willingly let me pick them up. Is it just a herding technique to try to push them back in the general direction of the gate?
