Is there non-organic meat in Switzerland?
For fresh, organic, skinless, boneless chicken breast you can pay $27/lbs in the US at an upscale store. Or skin-on non-organic at Walmart for under $3.
I have no frame of reference for if that is the beast chicken you can get from a fancy grocery store or the standard chicken from a standard store.
Your eggs seem to be about 50% higher than US eggs right now. Which seems to work out to a similar multiple if your chicken breast prices are for high-end chicken in a high-end store.
