I had a barred rock hen that started to lose balance, and sitting down all the time, walking like eggbound. I have 13 hens. All the rest were fine. The barred rock hen got worse day by day and died . Later one of the other hens showed signs of limping, and sitting down frequently. I just happened to see one of the other hens pooping. There were roundworms in her poop. I researched, gave Wazine17. All is well. Please look closely at symptoms. I was about to treat for eggbound.I was wrong. Worms show symptoms of an eggbound chicken.
