I'm sorry to hear about your pullet.Please help. Yesterday my 12 week old hen injured her leg and the other hens were picking on her. The vet told me to separate and said she can't see her til Monday. I already had her separated in a run by herself, I gave her some B12 hoping that would help her get better faster but then I left to run an errand. When I got back she was having trouble holding up her head. She is still sleeping and it's almost 11 am here. She's been trying to get up but she can't to lift her head. I don't know what to do for her and I'm wondering too if maybe she broke her neck somehow after she was separated. Any guidance and all prayers are appreciated.
Thanks
Can you post some photos of her and her poop?
How long has she been outside?
What breed?
You mention she injured her leg - is there a wound or swelling or was she just limping?
The other picked on her - are there wounds?
She can't hold up her head and can't get up - I would try to get some Poultry Nutri-Drench into her or give some Vitamin E (400IU) and B-Complex (1/4 tablet).
If she is lame along with not being able to lift her head -unless she's been injured badly, Marek's should also be considered.
Hopefully with photos/video and more information, we can make some suggestions.
We met when I was 15 and got married when I was 22 so now at nearly 38 he knows what's up 

My stepdad always gets those 'cannonballs' but this time I told him no, no, no!
Aside from my mom being a gripey party pooper, it was humid and bug infested outside, it was nice. I stood and listened to the crickeys chirping and heard distant fireworks; looked at the stars and found 'the big dipper' constellation! 


to go pick peas. I sweat up a storm, but thankfully I had a bottle of water to pour on my head.
I get it, though! When I was 21 I ended up back home while working and going to school! It does sound as though your family is lucky to have you!
But then they tell me that I'll like it when I'm old. I can't help looking younger than I am,(not to mention plain looking
) I think I inherited that 'look-younger-than-you-really-are' look from my grandmother. She has been told she doesn't look her age.
