Things from my garden they snack on when they invade... (aside from tomatoes & cukes & baked squash)
LOVE (Concord & wild) grapes- (which we are using at the moment to administer powdered antibiotics to our rooster)
dried radish seed pods & mature sunflower heads
beans- in particular dried beans that I don't want them to eat
fresh sweet corn- they will try to run away with the whole cob
peas.. especially pea flowers
broccoli stems (they only get a little of this or the eggs taste weird)
pineapple (this they stole from the compost heap repeatedly)
melons of any sort- the scrapings of the seeds they love
(mine will eat squash seeds raw.. but like winter squash cooked & soft)
plums.. the little wild plums around here in particular (they are like candy- omg good)
cooked... potatoes, sweet potatoes, carrots, (one rooster likes parsnips- the others don't care), rutabaga, turnips (smallll amounts or funky eggs)
Something about the Concord grapes that mine go absolutely insane over. A lot of people around here have them.. they make a little juice & jelly with them.. and give away the rest... so we get 5 gallon buckets full of them. All of October they have purple-ish poop... mullberry is the worst as it seems to stain more.
If you are getting it from the store.. just be cautious as some produce is pretty heavily sprayed. Farmer's market's/ farm stands are another good place to ask about seconds.
In a few days.. we'll be loaded up with pumpkins from the neighbors as they take down their Halloween displays.
