I think i had finally came up with a solution to this. I dont know if you guys know this.Woah knowception but uh yeah since chickens are desendants from T-rex(Did you guys know that) And same as Chickens. T-rexs came from egss and laid them and all that good stuff. So basically the point is when the T-rex "evolved" into a chicken basically the egg came first when the evolution was complete and the chicken was no longer a dinosaur but a mammal....ok now my brain hurts. Thoughts?
