Why won't 1 hen go in coop at nite, hangs alone?

I'm sooo new to the chickie world but learning fast. However, I'm stumped now. Help.

This little hen received some kind of injury alongside the road when she was young. G'dtr rescued her and I nursed her back to the living....her neck seemed to be off to the side and kept twitching. I never thot she'd make it thru the nite but she hung on and soon her neck seemed to be back to normal. I kept her isolated in dog crate, but inside coop with other chicks. They grew larger during the healing time but Emma has never really caught up to them in size. You might say she is a dainty girl. Once I let her out loose with the others, I noticed she always seemed to remain off standish, outside the circle, very shy. When the flock rushed to me for food, she would get pushed aside and stay there. Not aggressive at all. I don't think she got as much food and water as the rest so I started trying to feed her off to the side. During nice weather she free ranges with the rest but never goes far from home. They have all returned to their coop at dusk. However, I would find Emma near the coop but many times, still outside. I would have to gently pick her up and place her on a roost. She is able to roost and able to get down from a high perch, but can't get up to a high perch. She has been very socialized with people, especially the 5yr old g'dtr, who plays with her like a puppy at times, placing her in a wicker dog basket with blankets and toys. Emma just lays there and goes to sleep. This is Emma's history.

What I'm concerned about now and don't know what to do is this.....it's winter, snowy and cold. She is NOT going to the coop at dusk. We have to go search for her with a flashlight. Last night she was on the edge of the road by the mailbox. After dark chickens cannot see, correct? There are tube lights on deck and I think she sees them but she did not even get close last night. So for the last three nights I have brought her in the house, first two nights I put a hen diaper on her and she's fine with it, walks around, eats, drinks, sleeps. Last nite I brought her inside again and put her in a small wood crate and covered it up so she could sleep. She definitely is a 'pet' to all of us, due to her dainty, sweet, shy nature. But I really do not want this to be a continuous thing, living in the house. I don't mind a house pet but the diaper thing is more than I want to tackle on a regular basis. And then what do we do when we are not home?

Also, when I brought her in last nite, she had fresh bright red blood on her comb and beak. I could find no injury or damage to her and she acted just as normal as she ever did.

I've read here where stress/trauma will change their behavior. I'm wondering if this is the case with her. But why would she NOT go to her coop at dusk? Has anyone had a similar situation and what do you suggest I do with Emma. If we don't scoop her up and bring her inside the house or coop, she will surely freeze to death...and there will be more tears flowing than I care to even think about. Thanks for your help.

 

Oh Lordy, I was afraid the 'pecking order' might be her demise and that's kinda what you are saying here. Would it be possible for her to have her very own coop and run....all by herself...or maybe with one other smaller chickie?

Is she blind? Gosh, I don't think so...how would you tell? She walks around out doors, pecks at things, finds her way up the steps on onto the deck and she tilts her head to check things out. I haven't seen her stumble or such. When in the house she's checking out the futon cover, pillows, curtains and then settles on edge of futon to watch everyone, sometimes closing her eyes to catnap.

I forgot to mention that we also have 2 dogs and 1 cat and none seem to bother the other.....dogs and cat will go into coop to check things out, sniff around, leave....and try to snag the goodies I've tossed in yard for the chickies....they kinda eat side by side. We have a field across the road with neighbors sheep and I've seen my hens exploring over there...as well as THEIR roos and hens coming over to OUR place...found the neighbors flock right in my run one day, before I had let mine out of their coop. All one big happy family. Except for my Emma.

Thanks for the thots! It helps to hear from others with more experience than I, for sure!
