I have an almost 10 week old Splash Orpington. I have no idea what to do for her. She's been "sick" for several weeks now. I have 6 chickens- she is the only Splash and the only one acting this way. She keeps her neck tucked in and her feathers fluffed out. The other chickens had been picking on her--holding her down at the neck and pecking her--She sits all by herself- and she seems very lethargic. We brought her inside, away from the other chickens- sometimes she acts ok, but then when she goes to walk- sometimes she just falls over like she loses her balance. How can i help her????
