I have a 5 day old silkie chick that was rejected by my broody hen. I now know why, its way smaller than its sibling and after I seperated it it was eating as if it were starving, then started gasping for air. I could see a lump of food at the back of its throat so I got the tweezers and gently tried to remove it. The crop was not filling up. What could this be, will she die and is there anything I can do? Its so tiny
