I've had 2 hens for a year now. They were pets really but the eggs are nice too. I lost one...she just died for no reason I could tell. Now I have 1 hen. She comes in the house and visits, chases the cats and dogs and is pretty fiesty. She's a 4 yr. old buff orp. I've had since she was a day old. Do I need to get her a friend or can she be alone? She's been sitting on her eggs without coming out for days now. I've hand fed her in there and I'm worried she's lonely. Made her come out today and took her 2 eggs. What to do??? Thanks.
