Hello, I am a new chicken owner. Just for eggs and inadvertently pets. We got 6 chicks and one is a rooster now. They aren't yet 18 weeks. One of our RIR's has become almost completely lame in both legs. It started with just one foot and now the other. I don't believe it is a disease by the looks of her. She eats and drinks and tries to do normal hen stuff. Her feet just won't work they curl up under her and she trips on them. I had to carry her into the coop last night. The rooster has started picking on her too because she can't get away. I had already decided we needed to put her down as humanely as possible...but I am the type that has to put spiders outside because I don't like killing them. This is hard. Any thoughts...advice? It is almost like she has a spine injury...but I honestly don't know if they get those. Thank you!
