My hen is acting kind of oddly. She just stands there slightly puffed up and doesn't react to food. She lets other hens eat her mealworms even though she's one of the top hens. I think she's a bit dehydrated but she has been like this for the past few days. I put her in a coop alone with food and water with treats in it to tempt her to drink. Her crest is a bit shriveled but other than that, she looks pretty normal. I'll insert a picture of her.
