i have a girl that has been in quarantine for over a week now. We found her struggling to stand a week ago last Sunday and immediately isoalted her. No other issues in the flock. She cannot stand and tends to scoot on her side and keeps her head turned to the right. We have been giving her nightly doses of B12 and polyvisol. We started St John's wart 3 nights ago. She is eating and drinking while not as much food considering she isn't running around a lot. She gets pissy when we give her the vitamins by syringe and tries to flap her wings. We do prop her up when we see her on her side as we know that is bad. She really hasn't gotten any worse or better and I dont' want to give up on her but also know that some times they don't recover from Marek's at all. I also don't want to have her suffering if she is at all. It seems like Marek's to me......any advice would be helpful and appreciated.
