My RIR hens went through a fall molt in Nov (actually stopped laying completely at 17 mos). Not one egg ! I have wormed them, upped their protein with soybean meal (the get egg crumbles & scratch & free range during the day). My other batches of RIR's layed up into the 5th year & never slowed down (maybe a bit) during molts & layed year round, no problem. My 5 mo old RIR have started laying. I'm puzzled , can anyone help ? Thank you in advance.
