Unsure about eggs, but they definitely have their own rotisserie chicken farm and plant.

Story goes that Tyson's chickens were becoming larger and larger and thus Tyson wanted more money.

Costco wants to keep the chicken at $5, so they starter their own plant.

This isn’t really true. Their eggs are purchased from others (same as other Kirkland branding) and the chicken op for rotisserie is only a fraction.

If you live near a Costco, you can. The one near me is opening in a week, and I can't wait.
