ok, so i didnt know where to post this so ive posted it in emergencies aswell, ive noticed that my silkie chick is not behaving the way she usally does, shes quiet and not fighting for treats like she should be, and when i pick her up there is no fuss or noise she just sits on me really quietly, she is 7 weeks old , none of the other chicks have any symptoms and are litrally walking over her, ive have checked for any marks, mites ect but nothing, she is eating and drinking but not as much as usual, ive been watching to see if her poop is ok but she hasnt done any for a while but there is no sigh of different poop in the pen, can anyone please advise and help is better than none
