Orp around 4 months old. Eating and drinking just fine. Not positive she has marek's, no leg sprawl but walking wobbly. I don't want to remove her because she has never been seperated from our other orp. She gets distressed when I even pick up the other orp. What can I feed her to help? I read gaterade type stuff? Someone else said selenium for sick bird in general, I have some of that but how much do you give? Advice?
