Mine love tomatoes too. Last year, my husband and I were trying our hand at gardening for the first time, and we planted 20 tomato plants. They all did very well and we had hundreds of tomatoes all ripe at once. We had so many that even though I was stewing constantly, we could afford to be very picky. If one was partially slug-eaten, we threw the whole thing to the chickens (we will be much stingier this year, and cut off the bad parts; we only planted 5 tomato plants this year). Our chickens really enjoyed the daily tomato toss.
They ate all the blueberries and raspberries off our bushes before they were even ripe last year, so this year they are kept away from those bushes. They adore plums, cherries, peaches, and soggy old banana.
Oh hey... I bought some black oil sunflower seeds (BOSS) yesterday and gave it to my chickens. They were like, what the heck is this? They were NOT impressed. I thought, based on other comments, that they'd be nuts for it. Guess I was a bit disappointed they didn't like my gift.

Maybe it's an acquired taste?
