I have a golden comet pullet and she's just a little over a week old. I got her at a feed store with a few others and they all seen perfectly healthy, but at random moments she will just flop on to the ground. I've never had a chick do that before, and besides that she seems perfectly healthy. She almost acts like a fainting goat... She'll just be doing something normal like running around or eating and then all of the sudden she will flop onto her side with her feet and wings awkwardly sticking out, then get up and pretend like nothing happened.... just wondering if this is something I should be worried about.... Thanks in advance.
