I have a 10wk old Lavendar Ameraucana that is struggling to grow, seems to have a bad right leg (can't roost at night), and to the best of my knowledge, is having what appears to be regular seizures. She eats and drinks plenty and does her best to keep up with her siblings (she's one of four), but she's half their size and is picked on by the older birds. She's always been smaller, but has had these other "symptoms" for the last week. I keep struggling with whether or not to give her a chance or cull her in case she's miserable. She flips out if she's separated from her hatch-mates, which makes me believe that she has not completely lost her mental capacity, but I would hate for her to die and be in pain in the process. I've read on various threads that Poly-vi-sol (without iron) might help and that Hypericum could help if it's neurological. What would you do?
