No, it's not only the fact that it can suffocate, it's also that it can cause crop impaction or an occlusion further down in the digestive tract. You can't use anything that is not completely digestible. Not even when it says biodegradable because that only means that, given enough time and the right type of bacteria, enzymes, etc, it would decompose in nature but that could mean three months and birds don't have three months to get rid of what they ate, they only have three hours.
