Trying to reintegrate healed hen

[1NurseRatched]

My hen was attacked by a bobcat ten days ago and is fully recovered with no wounds (per the vet). I've kept her in a dog carrier inside the very secure run with three of my older hens (not her former roomies as the rooster lives with them and he was aggressive toward her two days ago while they were free ranging) for two days. She really wants to get out of that carrier and I want her to be able to get back to normal life, but wonder if two days aren't enough with the three hens. Furthermore I'd like to let her stay out in the run, in the carrier, overnight tonight (with food and water) but the roost is too small for the carrier, so she would have to stay on the ground. Last night when I went out just at sunset she yelled at me and I brought her in the house and she slept in the big box we had for her while she recovered - then this morning she raised bloody hell at sunrise - trying to crow (which she hasn't done before this). Sorry for the long post - can I leave her on the ground in the very secure run in the very secure carrier overnight? And for how many nights before I tuck her in the roost with the three other hens after dark?

You can leave her in the crate in the secure run on the ground. I have a broody in a breaker out in the secure run where I keep them. No problems there.
DO NOT just stick her on the roost with the older hens after a few days.
Did these older hens know her at all before she was attacked?
How large is the run and what is in it?
How large is the coop?
Pictures of the setup would help greatly.
How are the older hens behaving towards her while she is in the crate?
It is ideal to allow at least a week of the "look don't touch" portion of integration before releasing the new comer into a large run full of things to perch on, hide behind and scratch through. Let her roam the area by herself for about an hour before releasing the original flock and then stick around and monitor the first interactions. If no blood is drawn and she is not cornered and beat down, then leave them to work things out. I would also leave the crate open in the run so she can choose where she wants to roost.
Incidentally, if your run is truly predator proof, there is no reason to close the pop door at night once they are fully integrated.
