We have a two week old baby chick that somehow injured herself in the night. She is with two other baby chicks in a storage box with a heat lamp about 3 feet above them in our kitchen. We realized that after the injury, (or maybe the cause of the injury) the other chicks pecked her on her sides and she has feathers missing and one side is worse than the other. She limps on the side that is worse. We are not sure if her foot or leg are broken, or if the damage is above in the muscles that connect to her leg. It has some scab from light bleeding, but has not bled since the injury two nights ago. She shakes and pants most of the time, except when we hold her. She is the same distance from the heat lamp as the others but they are not panting like her. She eats, but very little, and drinks a little too. Has anyone experienced this? This is our first time raising chickens, thanks for any advice.
