Most of you are going to look at this and think I'm stupid, but I've got a battery hen that we rescued about 7 years ago. She sleeps on her own in a roosting box where as all the others sleep cuddled up together away from her, she's quite thin and I was going to get a chicken coat for her so she doesn't die from cold, but I was told my family that it would be cruel to pro long her life but I don't want to let her die painfully and having her neck snapped just isn't an option to consider.shes still got life on her and has a good quality of life, so could I feed her a few fat pellets in with her diet to get her to put some weight on?
