Possible shock? Video included

So it has been wet and rainy and chilly in my area of WV and my chickens have been doing fine until today. I heard my polish hen making a distress noise almost like a little cry she was puffed up and seemed cold, and when she saw me she huddled by my leg I put her in the coop several times but she kept following me I finally brought her in and I slowly warmed her up and placed her in an old brooder box in front of the heat and left her be while we went to church. Came home and really thought she was dead she was laying on her side but when I opened the box to pick her up she kicked her feet and then oddly twitched her head. Now she seems to be fine she is standing with her head tucked into her back part of her wings. It almost seemed like thats what she wanted to do when she was twitching her head but just couldn't find the strength and balance to do so. Has anyone ever seen this and does anyone have suggestions on how to help her or make her more comfortable?




Here she is acting fine with her little face tucked in like she is going to sleep this his how she has been for the past half hour

 

No new birds, and she was hatched early march, she is definitely staying inside until she is better, now she is falling over again I've never seen anything like it, its driving me nuts I feel helpless,

 

That sounds exactly like what she is doing, is there anything special you did for your bantam or was it just a wait and see game

 

She didn't make it thru the night
