So i have a 3 week old silkie chick who is hurt. My 4 year old nephew was throwing rocks into the brooder and hurt her. She has a cut on her leg and doesn't want to move much. She wont follow mama around. I have her in the house atm with a heat lamp and vitamen water and feed. What else do i need to do? Please help. She is just laying there on her belly fluffed up and cherping.
