Hi, I have a chick from Meyer hatchery. She is 3 weeks old and I picked her up shortly after hatch. She lives on pine shavings with the other chicks. I believe she is a Sumatra. She is very small, much smaller than the Welsummers the same age and about the size of the Hamburg chick. Today I took them outside for a little run on the grass and noticed the Sumatra was limping and holding up her foot. I checked it and her toe is swollen badly. She is eating/drinking normally but trying not to walk on her foot and laying down a lot. Her toe was orange with a little black when we were outside but by the time I got pictures taken about 1 1/2 hours later it was blacker. I have Hibiclens (chlorhexadine) antiseptic so I soaked it about 15 minutes in a Hibiclens/water solution and put her back with the others. I have antibiotic powder from Tractor Supply that I could mix up and give her orally. Does she need oral antibiotic? Should I try to lance it? Her toe is so tiny!! Should I isolate her? She is a quiet little thing and seems a little nervous so I'm not sure she'd appreciate being alone. Any suggestions would be appreciated! Here she is a few days ago out on the grass. She is very cute!
