Can we eat this chicken?!

[Chocolateporridge]

I bought a big packet of chicken breasts on Monday, they have a use by date of Monday. We opened the packet on Fri and used half, planning to use the rest yesterday (sat) but we didn't get a chance. They've been in the fridge and look/smell okay, can I use them tonight?

If they look and smell ok then they'll be fine. Go ahead and cook them.

You mean use by tomorrow? That's fine.

Well we ate it and we're fine phew,

No.
