Is it unethical to mix eggs and chicken?

[Halifax]

So I went through the drive through at McDonald's, to try the chicken mcmuffin. I thought that since it was breakfast, it would include eggs. It didn't include eggs. Only mcmuffin and chicken.

I should expect eggs, right? I couldn't understand why I didn't get eggs.

But then I was thinking that maybe it's because of the mix. Because it's a mommy chicken mixed with an egg.

like feeding cows cow, which lead to mad cow?

Thoughts?

I bread my chicken by rolling it in southern fried shake and bake instead of butter using egg yolk mixed with Soya sauce and then rolling it in Panko and a salt/pepper mix before I crisp it in a pan full of oil(don't have a deep fryer) and then bake it for 13 more minutes.

So zero fucks given.
