So I ran out of food for my pet hen and improvised, feeding her cheerios. I have chicken food now. BUT SHE WON'T EAT IT SHE WON'T EVEN TOUCH IT. It's the same food she's always been eating and now she won't even taste a bit of her food! I thought she wasn't hungry, but she saw me eating cheerios so I gave her some and she gladly gobbled them all up! She can't survive on just cheerios so how can I get her to eat regular food again? She started laying last week if that means anything.
