I've been watching a few of my girls for a few days now, and I dewormed them last night, so I stayed in the coop with them to make sure they all drank. Everyone drank fine, except one. She kept eating, and gasping every few seconds, almost like it was hard to eat. I noticed the other day that she regurgitated food, but I figured it was just too big of a piece for her. She thin, lethargic, and just refuses to drink. her crop emptied fine, and this morning I brought her in and tried to give her water via dropper but she still wouldn't drink much. I tried to offer her some water-soaked bread but she wouldnt eat it. I don't know what to do anymore, her comb has good color but she just seems so so sick.
