I don't know about tantrums, but I've definitely received the stink eye, and on numerous times been followed around and yelled at repeatedly, lolRight now, they're grounded with no treats for at least a week. But normally I do limit them, exactly as you said (even have my handy 3/8 cup for 3 birds!)
Do chickens tantrum? They're not handling their treat ban very well. I just went in to clean up poops, and one had the nerve to fly at my head! EAT YOUR FOOD!![]()
