I am new here and to raising chickens. We have 30 all total. The first 6 have been nothing but fun. We have 24 - 7 week old chicks. One got out of the brooder pen without my husband noticing when he was cleaning out the water & feed this morning. We found her about 1 1/2 hours later with her leg caught in the electric netting. Got her out and separated her from the others. Got food & water for her. She is eating & drinking but can't fully stand on that leg. The leg itself looks pretty good but the foot is swollen and looks like fluid has collect in the ball of the foot. We rubbed it with arnica gel hoping that wuld help with swelling and inflamation. Anyone other suggestions would be appreciated.
