We just received our first chickens! They are such wonderful ladies and we have grown attached to them already. One of them, a rhode island red, does not seem to be doing so well. She is around 22 weeks. They just moved from a 20-acre free-range farm to our small backyard, so she may just be depressed or adjusting to her new environment. The other five are all doing well, but she is seems very lethargic and has a really messy bottom. Her tail feathers are very droopy and she shakes a clearish liquid that seems to be coming from her inside her beak. We received them four days ago and she has not laid an egg. She is drinking water, but is not eating much at all. When we throw a worm right in front of her, she does nothing. We went ahead and separated her from the rest of the flock in case she has something contagious, but I do not want to stress her more. Any thoughts??
