What came first?

I have chickens. 4 to be exact. They are really incredibly funny animals to watch. ----more---- It turns out they are cold blooded hunters. Kind of like mini- T-rexes. They recently started laying eggs for us. We are very excited. But I now can say with some authority, In our case, the chickens came first. And if you want to know why they cross roads – it’s to see if there are any bugs on the other side. You’re welcome.
