I have 15 birds ( Barred rock and Americaunas). The girls layed eggs through the winter last year with no problem . This year was the first time I have seen them molt. The whole flock molted and they look wonderful and fluffy.As soon as they started molting they stopped laying eggs. This I understood.They are now done molting, and only the one Sexlinc chicken and one young Americauna is laying eggs. I have replaced all the bedding in the entire coop.I have put fresh herbs in the coop to entice them to lay there.I am leaving about 5 eggs in two different spots to entice laying.They eat layers pellets daily. I occasionally offer oyster shells and egg shells ( from the store ) , and they kinda peck at them. There are always some left, so I don't think it is a calcium issue.?? I have only had chickens for two years so still kinda new . Any good info would be great. thank you!
