I have been reading the topic of "treats" and I just wanted to know if there is anything that is bad for chickens to eat. I can understand the obvious like chocolate or meat products, but I have a silver-laced wyandotte and a black australorp that eat almost anything! I just gave them some yellow squash and they fought over it. They love watermelon, tomotoes and over-ripe bananas, too. Thanks for the info!
