Chicken and Cow Egg Tight Fit Shirt

For most of the last two years I have notice my beautiful cow Mabel, and favorite chicken Betsy had been spending a lot of time together.

Although I thought it was a bit strange, I was thankful it was not the weirdo creep Gonzo that used to hang on the chicken coup doors trying to chat up the ladies.

Last week I went out for a walk around the farm, and this is the site I ran into.

This whole thing is very confusing to me, I don't see how a cow and chicken could make such an egg, and really I think poor Betsy and Mabel are even more confused than I am.

I wonder if I feed the creature that hatches from it chocolate, will it lay milk chocolate eggs?
