My main flock of 19 layers is back up to 12 laying again. That includes many in the 3-5 year old range. I have three other groups as well, but many of those are younger birds.
Good for those girls! I'm seeing my old ladies, 3 to 6+, each laying 3 to 4 eggs a week now that they are done with their molt. Well all except Drucilla who is still mothering her daughter, Pip, who is now laying too.
