I agree, let it be. Her lungs are probably fine--do let us know how she does!Not sure about the crackling in her lungs. I hope it clears up quick! As for the piece of egg and stuff attached, I would just let her be at this point. It will dry up and fall off eventually. Hopefully sooner rather than later. I'm not sure how to do the dental floss thing. I've always just let things dry up and fall off. I've had a chick that had a string thing dried up on it for about 4 days before it fell off. lol
