I bought 6 silkie chicks from a local breeder a week ago. all of them have been fine til today. One of them is continuously opening his beak and seems like he's gasping for air. He still cheeps some, but is not eating or drinking. We used a little veg. oil to see if maybe he had something stuck in his throat (because that's what it looks like) but no change. He isn't moving around much and he has his wings drooped out away from his body. These chicks are only a couple of weeks old, so they are super tiny. I feel aweful because I don't know what to do for him. HELP!
