...So Yeah, The chicken.
That is absolutely retarded. No bird can mate with a chicken-o-saur. Just as no bird can mate with a dog.
To answer this question, you must first accept that all life on the planet evolved from single celled organisms which multiplied, had beneficial mutations and eventually their distant offspring turned into multi-celled organisms. You must also accept that this started in the oceans. In the oceans, soft-shelled eggs prevailed over regular birth and hard-shelled eggs. Eventually life came out of the oceans, at first as amphibious creatures, then as time went on, animals became ectothermic, to fit in with the ever-changing environment. Ectothermic creatures are 99.9% of the time oviparious today(ovoviviparous species are extremely rare, found only in some species of sharks and some lower reptiles.) This was not the case back then, as a lot of species back then were ovoviviparous, as the predatory organisms had not caught up. When that happened, the ovoviviparous creatures began laying their eggs in nests, in order to be able to protect them, as you can't really fight off a giant manbearpig with an egg in your lower abdomen, can you(metaphorically speaking)? The creature(chicken in this case) came before the egg.
