Injured Bird--Chicago, IL

[amazia]

Hello...I found an injured pigeon near the El Friday, Feb. 25. He can't fly and is barely using his left leg to walk. I used your "basic needs" advice posted by maryco. He's eating (millet and black oil sunflower seeds) and drinking water. I started him on pediolyte today, so far about 2T. He's being kept warm in a big boot box with shredded newspaper and I used a 20 oz pop bottle to store hot water (covered with a sock) for him to cozy up to.

He's a great guy, but I don't want him to become domesticated. I'd like him to return back to "the flock" at some point. I want to take him to a wildlife rehab center asap...any suggestions for the Chicago/Cook County area?
Also, how can I check for injuries?

Any help will be appreciated!
