I have a 3 week old chick that used to be with 12 other bantam chicks that I ordered online from ideal. All 13 were perfectly healthy but now I realized that one is shivering uncontrollably, she won't eat or drink even when I dip her beak in the water she just refuses to drink and will shake her head away from the water. And I have not seen her eat today. I separated her from the rest of the chicks fearing that it could possibly be Merricks. (though I had them get a vaccine before I ordered them.) her eyes are clear and when I was trying to get her to drink she was standing normal and suddenly leaped into the air into the sink and could not get out of the sink so I helped her out. So she can move her legs and wings and her eyes are clear so it doesn't sound like Merricks. So what else could it be? Dehydration? Any help would be nice. Thank you.
