Previous post https://www.backyardchickens.com/forum/viewtopic.php?id=413838 Please read for back story, or else this post won't make sense. I have another hen ( 2 year old Cochin) that is going down. Breathing is labored, and she is skin and bones. I have made sure we do not have worms in the flock for sure. Feed is what we make ourselves out of high quality local grains and fishmeal. Dry deep litter in coop. Waterer is clean.
