What can't they eat???!?!?!?

I'm curious as to what chickens cannot eats ( like dogs can't eat grapes or raisins). Now I'm nit talking about the obvious; candy, chewing gum, poisonous substances etc., but in terms of actual food items. Any replies will be greatly aporeciated!!!

My dogs eat grapes and raisins... My chickens eat everything from standard feed, to ... well... cooked chicken. Favorite treat is cooked pasta or a head of cabbage.
Mine are not fond of beans or onions, but adore steamed clams and quahogs... But I fear if I stumble and fall I would be considered an entrée...

Grapes and raisins are highly toxic to dogs. They can cause adrenal failure. Onions are bad too they cause Heinz anemia. Just sayin'. I only know this because I am a dog nutritionist.

Our chickens pretty much eat everything and anything. Cat food is their preferred treat and will run the cats off from the food bowl to have their share. Kind of weird but all our birds are healthy and happy and active and laying very nice large quality eggs for us so ... onions can give eggs an off taste and our chickens don't tend to eat them. They don't like carrots or bready things like pancakes and blueberries tend to be left behind. Strawberries and tomatoes are their favs.

On the dog note, chocolate and onions are the only substances that are actually toxic to a dog ... my mom's a vet. Grapes can cause dogs to form crystals in the kidneys. Just saying ...

Can't remember what's in it but don't feed alot of cat food..a can now & then for protein is ok. Garlic, Onions, and anything strong flavored will taint the taste of ur eggs just like breast milk. Green potatoe peelings will poison any animal.

Raw potato skins. You can nuke the skins in the microwave and they are fine.

About the only food thing I don't feed is avocado. (like they would get past me ) Some people have said the peels and pits are worse than the flesh.

My Mom, (gone now) always gave her chickens what ever was left over from the kitchen. that included potato peelings.......she had chickens for over 50 years since I was little. I never saw or heard of any problems with her chix and she always had more eggs then we could ever use. She gave the extras to a orphanage near us.

My mom also always feeds her chickens whatever scraps she has from the house which includes potato skins. Has her whole life. And I believe my grandma did too. And now I do too. Never caused a problem for us.

This is a list I copied from one of the BYC threads....https://www.backyardchickens.com/forum/viewtopic.php?pid=188621#p188621 However, when I clicked on it again, it didn't open???????

Ii just found the thread....https://www.backyardchickens.com/web/viewblog.php?id=2593-Treats_Chart This is the same chart but updated.

This is a list of everything you can feed a chicken. However, everybody's chickens have their own tiny brains full of likes and dislikes, so while one person's chickens may come running for grapes or watermelon, another person's chickens may turn up their pointy little beaks at it. Anything on this list is worth a try. Your comments are welcome - please post them on https://www.backyardchickens.com/forum/viewtopic.php?pid=188621#p188621
At the bottom of the page are things you should avoid feeding your chickens.

Treat
Apples Raw and applesauce Apple seeds contain cyanide, but not in sufficient quantities to kill.
Asparagus Raw or cooked Okay to feed, but not a favorite.
Bananas Without the peel High in potassium, a good treat.
Beans Well-cooked only, never dry Also, greenbeans.
Beets Greens also. .
Berries All kinds A treat, especially strawberries.
Breads All kinds - good use for stale bread or rolls Feed starches in moderation.
Broccoli & Cauliflower Tuck into a suet cage and they will pick at it all day.
Cabbage & Brussels Sprouts Whole head - Hang a whole cabbage from their coop ceiling in winter so they have something to play with and greens to eat.
Carrots Raw and cooked They like carrot foliage too.
Catfood * (see bottom of page) Wet and dry Feed in strict moderation, perhaps only during moulting * (see bottom of page)
Cereal Cheerios, etc. Avoid highly sugared cereal such as Cocopuffs, etc.
Cheese Including cottage cheese Feed in moderation, fatty but a good source of protein and calcium
Cooked Chicken . They may like it and it won’t kill them, but it just seems so….. ummm………… wrong.
Corn On cob and canned, raw and cooked .
Crickets (alive) Can be bought at bait or pet-supply stores. Great treat – provides protein and it’s fun to watch the chickens catch them.
Cucumbers Let mature for yummy seeds and flesh.
Eggs Hardcooked and scrambled are a good source of protein, and a favorite treat. Feed cooked eggs only because you don’t want your chickens to start eating their own raw eggs.
Eggplant . .
Fish / Seafood Cooked only.
Flowers Make sure they haven't been treated with pesticides, such as florist flowers might be. Marigolds, nasturtiums, pansies, etc.
Fruit Pears, peaches, cherries, apples
Grains Bulgar, flax, niger, wheatberries,etc. .
Grapes Seedless only.
For chicks, cutting them in half makes it easier for them to swallow. Great fun - the cause of many entertaining "chicken keepaway" games.
Grits Cooked
"Leftovers" Only feed your chickens that which is still considered edible by humans, don't feed anything spoiled, moldy, oily, salty or unidentifiable.
Lettuce / Kale Any leafy greens, spinach collards, chickweed included. A big treat, depending on how much other greenery they have access to.
Mealworms
(see photo after the chart) Available at pet supply stores or on the internet, although shipping is expensive! A huge(!) favorite treat, probably the most foolproof treat on the books.
Meat scraps of any kind. Not too fatty. In moderation, a good source of protein
Melon Cantelope, etc. Both seeds and flesh are good chicken treats.
Oatmeal Raw or cooked Cooked is nutritionally better.
Pasta / Macaroni Cooked spaghetti, etc. A favorite treat, fun to watch them eat it, but not much nutrition.
Peas Peas and pea tendrils and flowers (thanks to YayChick for the advice) .
Peppers (bell) . .
Pomegranates Raw Seeds are a big treat.
Popcorn Popped, no butter, no salt.
Potatos / Sweet Potatos/Yams Cooked only - avoid green parts of peels! Starchy, not much nutrition
Pumpkins / Winter Squash Raw or cooked Both seeds and flesh are a nutritious treat.
Raisins .
Rice Cooked only Pilaf mixes are okay too, plain white rice has little nutrition.
Scratch Scratch is cracked corn with grains (such as wheat, oats and rye) mixed in. Scratch is a treat for cold weather, not a complete feed. Toss it on the ground and let them scratch for it for something to do.
Sprouts Wheat and oat sprouts are great! Good for greens in mid-winter.
Summer Squash Yellow squash and zucchini Yellow squash not a huge favorite, but okay to feed.
Sunflower Seeds Sunflower seeds with the shell still on is fine to feed, as well as with the shell off. A good treat, helps hens lay eggs and grow healthy feathers.
Tomatos Raw and cooked.
Turnips Cooked. Not a huge favorite
Watermelon Served cold, it can keep chickens cool and hydrated during hot summers. Seeds and flesh are both okay to feed.
Yogurt Plain or flavored A big favorite and good for their digestive systems. Plain is better.

Don’t feed the following things to your chickens:
(I'm sure people have experienced exceptions to this list, but if we want to raise our birds the best way possible, "better safe than sorry".)

Here’s why:
Raw green potato peels Toxic substance called Solanine.
Anything real salty Can cause salt poisoning in small bodies such as chickens.
Citrus .
Dried or undercooked Beans Raw, or dry beans, contain a poison called hemaglutin which is toxic to birds.
Avocado Skin and Pit Skin and pit have low levels of toxicity.
Raw eggs You don’t want to introduce your chickens to the tastiness of eggs which may be waiting to be collected in the nestboxes.
Candy, Chocolate, Sugar Their teeth will rot… No, it’s just bad for their systems, and chocolate can be poisonous to most pets.
