I'd really appreciate any advice anyone has to give. My chicken, Sassy, is now 20 weeks old. About 2 weeks ago she started having trouble putting weight on her left leg. She would kind of flop it when she walked like she had little control of it. The toes would all kind of curl, but would sometimes be straight and when standing still she would rest on her left hock while her right leg was straight. I separated her in a dog crate within the run because I thought it was a sprain and didn't want it to get worst by jumping from the roost or coop. A few days age she started having the same problem with the right leg. She is still eating normally and has normal poop but has a lot of trouble getting around. When she does attempt to walk she often steps on the other foot and stumbles. I started giving her riboflavin a few days ago but haven't seen any difference. I'm afraid she's suffering... It's my first time with chickens so I just don't know what else to try or if it would be most humane to put her down.
