Our hens are Isa Browns. They will be 2 years old this summer. They molted in the fall and really backed off laying for awhile. I was really surprised at how quickly they molted and started laying again. One (or more) is still laying smaller sized eggs, but we get an average of 6-8 eggs a day. I am surprised at how often we get 8 eggs with it being their second winter.Are your girls back to laying, yet? I'm mostly still waiting. I have one girl who laid fairly regularly, all winter. But her eggs are fragile. She has a shell-gland issue. Sometimes her eggs go to the dogs. And I have one who lays maybe once or twice a week - out of eight girls. Four hens will be 3 years old in the spring. 4 hens will ne 2 years old. They are all RIRs.
