Young chicken slowing down???

[CheerioTheBuffRooster]

I went out to the coop this afternoon to check on the chickens and my 6 month old Amerucana hen Hattie was sleeping standing up. I thought that was fine and normal but when I let the other hens and roo out, she stayed in and just stood there looking around. This was wierd and I knew something was wrong because she is usually the first to dun out when I let the chickens free range. I checked her over and physically she looks fine. I checked her vent as well and I didnt feel any eggs that could've been stuck. Could she have eaten something bad in the yard?? When I picked her up and put her with the others in the yard, she just stood there. The others moved on and she still wouldn't move. She didnt even dodge me when I picked her up. If anyone can help that would be great I cant stand to see Hattie like this, she is usually so perky and energetic )*:

So I just went out again and noticed that there was an egg in her vent so I massaged the muscles around and the egg came out. She then got up and walked away so I think that's a good sign?

She was probaly just egg bound

She got the egg out, but now she is just back to standing and doing nothing. I moved her into the coop to make sure she was safe and wouldn't get left behind again. She drank some water but it still not acting herself at all could it be an iron, calcium, or vitamin deficiency?
