I have 2 Brahama hens and a rooster, a Rhode Island Red and an Americauna. They were laying great all summer and then in October they all started to moult at the same time and quit laying. Haven't seen an egg since and it's February now! Is this normal? I live on Vancouver Island, BC. We tried adding hours of daylight for about 3 weeks in Decemeber but nothing happened so we stopped.
