Hello! I am in need of advice. August 5th of last year I purchased a few 4 month old Ameraucana hens and 1 2 year old laying hen. However, when I brought them home the 2 year old stopped laying, and the others still have not started. Is this normal? The other 7 hens that I already had stopped for a few months over the winter but are now laying again daily. Grateful for any advice!
