They could be a barnyard mix. Two rescued chickens (abandoned at a farm and when found everything had died except for these two - there were goats, chickens, horses, etc). They are full size, but I don't know what they are. The female lays a cream egg, medium I would say. No idea on the age, the female started laying after she was found, but she could have been not laying due to malnourishment. The roo hasn't been seen breeding the female though so maybe young?? They are my sister in laws now 
They are both gorgeous birds - the male has a blue "shimmer" that I couldn't quite capture in the picture:
