Over the years I develope a startegy where they won't even know when their food is coming. I stopped chopping chicken everyday, instead I chopped them into two ice cream buckets and store them. So all I have to do is cook rice and serve it with chicken and eggs.
Then I'll feed the ones out on the yard first since they won't be working out for the day. Once they're fed they won't care if the ones in the garage are getting worked on. I rotate them in and out every three days. I have all of mines on pre-keep throughout the year.
Also when they get their daily exercise, they seem to be more relaxed and lay back, up until they know it's time to work.
