Chirping
I got a new chook a few days ago and I'm not sure what to make of her behaviour. We got our new Orpington, Chestnut, as a friend to our lone Australorp, Peggy. I know we're supposed to quarantine any new chickens but we quickly learnt that Chestnut, farm-raised girl that she is, came with both Houdini-esque escape skills and a decided dislike for quarantine. And fences. And backyards in general. 
Anyhoodles, our chickens met and, metaphorical milk already spilt, we decided to just let them continue hanging out, monitor the situation closely and focus on cutting down the number of escape attempts.
We expected a fight for dominance but by afternoon on the first day the Pecking Order seemed to be already established; Queen Peggy was top chook and Chestnut was her new subordinate. They're fairly happy together, considering it's still the first week, and are already sharing a coop and run. But we have noticed some odd behaviour on Chestnut's part.
She seems a little too submissive for our tastes.
Is it just a settling-in issue? Or a pecking order thing? Will it fade in time?
Is this just a difference in personality?
Or is she unwell?

- She eats very slowly and significantly less than Peggy, pecking at treats several times before eating it, and that's the treats she does eat. As well as pellets and course mash, we feed them vegetable scraps (eg. bits of carrots, broccoli, fresh corn, etc) that Peggy will practically lunge at but Chestnut will often ignore them for a while before, maybe, coming back for a taste. We've had to feed them separately to make sure Peggy doesn't eat her share, but she still eats so slowly.
- She also seems too disinterested in what's happening around her. When I walk up Peggy immediately runs to me, especially if I have anything in my hands, but Chestnut often just glances up and ignores me, offered food or no.
- If she's pecking/scratching up a patch of grass and Peggy comes over to peck at the same spot sometimes she'll walk away and stand hunched over until Peggy leaves.
- Peggy will still peck at her from time to time, and while she'll try to move away Chestnut never pecks back at her. If she's in the coop with few escape options she'll just hunch over on higher ground and ignore Peggy.
- She's been unresponsive a few times to me, too. I once tried to hand-feed her while she was in this hunched over position and she not only didn't eat, she didn't even move her head away. I even tried nudging her beak to get a reaction and she just stared ahead.
