One of my Road Island Red hens is down in the dumps the last 2 days. Walking slow and shakes her head more often than the others. They are 13 mos old and for a treat I put them in our garden 2 days ago where they ate LOTS of worms. I have held her massaging her full craw, turned her upside down many times and she still acts like she does not feel good. All others are just fine. I held her yesterday for about 1 1/2 hours and she loved it resting in my lap and closing her eyes alot. I witnessed her drinking and pooping yesterday. Any clues out there?
