My 1 yr old White Leghorn started doing this yesterday at some point, I don't remember when - she has dirt and feed at the edges of her beak, scratches at her beak, and when she tries to eat feed, she opens her mouth and there's un-swallowed feed inside. She then sticks her neck straight up and opens her mouth and SQUAW-SQUAWKS. Sometimes, she shake her head and HONK. I've tried picking her up and feeling her neck, nothing unusual. I haven't seen her drink lately, but that's not unusual either. I gave the hens an apple to eat, and she (surprisingly) wasn't interested! She pecked, couldn't manage to swallow the small piece, and walked away. She seems to hiccup too... Also, I gave her and the others a warm flea/oil bath (she ran under a parked car that had been oil-guarded) with salt, vinegar, and Dawn, all very diluted. She was then rinsed in warm water, wrapped to dry, then blowdried. Should I try giving her water with a tiny dropper? I'm worried!
