Hen hurt BADLY....might need to be put out of misery?

My one and only beautiful big buff orp...didn't get in the coop on Tuesday night.....couldn't find her.
Figured she'd be okay, one of my older "more experienced" hens has done this and survived so I didn't
worry too much. Found her in the morning and she was bloody and couldn't stand. Brought her in the porch
with food and water. She'll drink if I wiggle my finger in the water, but still can't stand. The only wound I can
find is a cut (deep) right on her spine. Think maybe back is broke. She's alert and like I said will drink lots when
I take her out of kennel and show her the water. She won't eat. Made her scrambled eggs and she kind of pecked
at them, but that is it. Time to put her out of her misery?????

Sad.

 

Even if she can't walk? She's been in there quiet for 2 days - this is day number 3.

She lays with one wing half sprawled out. Her comb is still bright red.

I hate this part about chickens

What about something for pain? I did put some electrolytes in the water. Thank you everyone.

 

I did that this morning....also spread both wings out....seems to be missing alot of her feathers on her left wing. Does not have use of her left leg...it's not cold to the touch though. When I was trying to see her wound.....she didn't flinch...it's almost like she didn't "feel" anything. She will only drink when I tip the bowl. She cannot lift herself up to get in the bowl. That is why I'm thinking paralyzation. Is that even a word? She squawked when I picked her up this morning - to get her some water. But she sure drinks alot when I get her to. She stays in the same spot - unless I move her. I know this because her poop is in the same spot and there is no movement of the shavings. She's been in the same spot for this is the 3rd day. : (
