I would follow the same rules you do for yourself. For chicken, I personally would probably use it fresh, make some for the family for dinner that night, and use up any leftovers by the next day. I tend not to keep cooked meat as leftovers around for more than 24 hours. If anything, frozen and thawed ground chicken probably has a strange texture and not as tasty and nutritious as it would be made fresh. If you make it as part of your dinner anyway, there shouldn't be any waste. I often just cut a piece off of one of ours, as they often don't eat much as first anyway.
