i have heard you can even feed chickens uncooked rice... a lot of people say "NO!" because of the little birds that "blow up" from eating rice then drinking water. but have never heard of it happening in chickens..
Gave my ladies our leftover rice tonight, yea it is great they love it!!!. Uncooked rice in small fowl like pigeon is not a good idea, thier digestive tracts are not the same as chickens, I just would not do it for safety sake.
Birds dying from consuming uncooked rice is nothing more than an urban legend...which has been disputed by many scientific sources including Ned Johnson, the curator of ornithology at the University of California, Berkeley.
