Hello- My adorable and otherwise extremely healthy 3 wk old chick (1 of 3) suddenly is limping, falling over as she tries to move as usual. She obviously hurt her leg somehow and is off balance even in the large cardboard box with hay and food/water I keep them in most of the time with their adoptive Momma. She has been raised by my silkie hen and doing well until this morning when I let them out to free range. I saw that she had trouble walking, falling a bit and moved them all inside to be together. I put some vetrimycin on a tiny red spot on her mid-knee. She still tries to walk @ as usual and wants to be with her Momma hen. I'm worried. Any help/ideas for her????
