Nuts are fine for chickens.Yikes!! I don’t feed my chickens nuts! I don’t think those are good food items to give them as it is!
As long as you aren't selling eggs to anyone who is allergic.
I'd imagine they'd have to eat a fair amount to cause an allergic reaction like that.
Apple seeds are toxic, but they aren't going to be getting enough to kill them.
Tomatoes and potatoes can be toxic.
They say don't give your chickens any scraps you wouldn't eat yourself. That would include raw potatoes, apple seeds and underripe tomatoes.
