Hi all! I am needing some advice. But first, let me give you some background info. We began raising backyard chickens in July so we are very new to this. We started with 4 2-week old chicks. We have an Australorpe, Silver Laced Wyandotte, Golden Comet and Rhode Island Red. All very spoiled and loved on by our family including our children. Sadly last week my 11 year old rushed through checking them into the coop and she left her Red out. A raccoon got her overnight and we are all devastated. We decided to go to a local farm that sells eggs and chicken meat to get another Rhode Island. She is 7 months old and laying. Our remaining 3 are just now 5 months old and not laying yet. We have kept them separate at night and allow them to roam freely together during the day. The first day had some issues, but they have all gotten along now for 4 days. Problem is, I get the feeling our new hen may be sick. She is older, but a lot smaller, her legs have an odd pasty white color (our first Red had beautiful golden legs) and she does have some diarrhea. We have her on our back porch to watch her and sometimes she has normalish poop, other times it is almost just water. Any ideas on what we should do? Thank you in advance!
