During the winter I've been feeding the girls two "hot meals" to help them stay warm and productive. These are in addition to their corn/crumble feed. They get half an apple, or a small potato chopped (not too small), two slices of toast cubed, some fat (bacon or sausage grease, canola oil, meat trimmings) and appropriate leftovers. We never leave french fries, or anything else, in a restaurant anymore. It all goes into the doggie bag, chookie sack. They also get cantaloupe and pineapple trimmings, dried out cheese, tag ends of boxes of cereal and crackers. They get any really dirty eggs right back scrambled and mixed in their extra meal.
During the summer they are not going to get the extras, but they'll still get the veggie trimmings, some bread or crunchy starch, and the favorite, Corn on the cob. It's amazing how much they get off a cob which you've just cleaned off for dinner. There's usually a few halves of ears left over besides the ones we've eaten.
If I could only get them to eat slugs.
