McDonald's has a slight inventory dilemma on its hands. A 10 million pound inventory dilemma. McDonald's Mighty Wings, which were released nationwide this September, turned out to be a major flop, and now the fast food chain has huge stockpile of frozen wings it needs to get rid of, the Wall Street Journal reports.

After purchasing 50 million pounds of the bone-in chicken wings, McDonald's didn't to sell enough of its limited-time product. Now it is stuck with about 20 percent of the original inventory. What went wrong?

It's not a taste issue -- The Huffington Post found the wings to actually be quite tasty. And we weren't the only ones.

It wasn't about the advertising either, which may have been a little off at times.

The wings were too expensive. At more than $1 per wing for orders under 10 wings, the price "was not the most competitive," Don Thompson, McDonald's chief executive, told Bloomberg Businessweek. Three wings were sold for $3.69, five for $5.59 and 10 for $9.69.

McDonald's will now sell the wings at a discounted price of three for $2.99, according to the Wall Street Journal.

Judging by the frozen McRib photo we saw last month, we don't really want to imagine what 10 million frozen chicken wings looks like.
