I agree with KK, corn husks are not recommended for rabbits. Though organic does eliminate the pesticide worry, it still doesn’t eliminate some of the other concerns – Here are some of the reasons stated from different rabbit savvy experts/sites:
This one is an answer that Dana Krempels (rabbit-savvy expert) gave regarding feeding corn husks:
“I would not give them corn husks for two reasons. First, they are very stringy, and hard to chew. Since I know of bunnies who have gotten the strings of celery caught on their teeth and caused serious problems, I would think the same thing might happen with corn husks.
…….I just wouldn’t feed them to my bunnies when there are so many other good things to feed them”

“Whole Kernel Corn of any kind (fresh, frozen, or canned – even the husks around the kernels can cause impaction)“

Though I am sure there will be sources that will say they are just fine, any time I feel that there is some strong question, I agree with Dana that there are other good things that I know for sure are okay. I’d rather stick to that.
