A few days ago I went outside to let the birds out. Unfortunately one of them died in the coop. It was alive when I put them in the coop, but wasn't the morning after when I went to let them forage. After the chickens death, one of my hens has been constantly tired and sleeps often, will only forage for a little bit, still eats but many chooses to lay around, seems sad and acts different, and may have lost weight I am not sure. Could she be depressed or have some sort of parasite. Please I need answers for I don't want to lose this beautiful chicken.
