Thanks in advance for any help. This is my first chicken injury. Pullet is a 15-wk old Cream Legbar. I noticed she was sitting today a lot today, but she seemed to be getting up now and then, and I saw her eating. But when I checked her out this evening, her leg, especially the thigh and adjacent part of her body, is VERY soft and puffy, like a massive infection. I could not see an injury, but could have missed a deep puncture. I don't think the leg is broken or sprained, as she can walk almost normally. It feels almost like it has fluid in it. It is not her abdomen, but her thigh. I'd appreciation any tips on what to do. Try harder to find an injury? Antibiotics? Epsom salt soak? Is there anything over the counter I can get at the farm store to treat her, given tomorrow is Sunday? I have newly integrated her and others with an older flock, starting gradually weeks ago. The integration has been going well. I have not see anybody going after her, and I have ample space, but perhaps she was injured by another hen.
