I say HEN! I have RIR, BR, & Delawares. I got them all as day old chicks, and they matured at different times. I would say that you should be getting an egg any day now! Some were a lot more red and larger than others. Those girls started laying eggs first and then the others caught up and looked the same. So I would say to start looking for eggs!
Hope that helps!
