i don't see why not. just check the ingredients lists first to make sure there aren't any chicken no-no's in your particular baby food, and don't give them too much at a time since they're probably not used to concentrated fruits
(conversely, if they're unopened jars, you may also be able to donate them to a local women's shelter or something. i only suggest because baby food is a pretty pricey chicken treat, when there might be people in need
Yeah its good for them & tuna, corn on the cob, melons, blueberries, strawberries, steak, pork (let them peck at a big piece of meat), and many more just dont give them salt, sugar, chicken, eggs, avacado, chocolate, raw nuts, citrus, raw potato/beans.
They love eggs!! Hard boiled, or scrambled and then mash them up as an occasional treat. The totally dried and crushed egg shells are also good for them!
