I have a flock of 15 EE chicks. They're just over 4 weeks old. So cute and healthy! However, one of them has been odd since she arrived, and is now starting to worry me. She was slower than the rest from the start. As she's grown she's slowed down. She waddles. It almost looks like it hurts her to walk. She's also a little "hunched". I'm wondering if she has some kind of birth defect perhaps? She eats and drinks fine. She's just getting slower every day now. She walks a little ways, then sits down. It figures - this very one was my daughter's favorite - also from day one - due to unusual markings. As she's feathering in she's so pretty and brighter red than the rest - but - I fear for her. Anyone?
