I have the same dilemma. I wish I knew how old some of my chickens were too, I just got a road island red she is full grown but doesn't appear to be all that old, but mot one egg from her. She is with Grrrtrude another one of my girls who I had to remove from the coop cuz original flock didn't like them so I know for a fact neither of these girls are laying. Also how old so silver laced, astrolorps, and jayhon need to be before they start laying. I have been a hobby farmer for about 6 months and have lots to learn.Thanks for any ideas on ages or when my pulleys will lay
