Feet are a great clue to their past. These pair belong to Branwen. Note the sharp claws at the end and scaly skin. Not unlike the Archaeopteryx below - one of the first fossilized birds.
Then there is the Gallimimus which is closely related to the ostrich. Part of the Ornithomimids group and very similar to our ground living birds with a lightly built skeleton, long neck, compact body, small skull and beak.
Note how long my hens necks appear on this photograph and quite similar in structure to the ancient Ornithomimids.
That's the science bit - now for something eggstra!
Dinosaurs laid eggs to hatch their young - just like my girls - I am a little concerned about what is hatching inside the chicken coop though.
Could this be the start of something new? There are dinosaurs all over the place.
Blodwyn is not too happy about sharing the coop with a stegosaurus.
That may be that he is not such a close cousin as the mighty Tyrannosaurus Rex. At least she has the upper hand now, as after 100 million years, she is a lot larger, so he is no competition for her.
The Dinosaurs may be extinct, but some of their characteristics live on in our feathered friends. Watch out for that broody hen or the ferocious cockerel next time you go inside the chicken coop.
