good morning: i have a 2 1/2 week chick. s/he was fine this morning - running/being a general maniac per usual. then, i fed them some yogurt (plain, organic). now, s/he acts drunk - - tipping over to either side, and even to the front. s/he ate the yogurt fine and i've not noticed any "strange" behavior up until now. any ideas, suggestions, things i should do or look out for going forward?
