With marans the longer they hold out normally the dark the eggs will be when they do lay. 7 months is not uncommon. Mine normally start getting mated on a week or 2 before they start laying. This is just something I have noticed. So if there is mating going on for a while then they are hiding them or just havn't started quite yet. Maybe lock them up for a few days and see if you get any eggs, You may be suprised. Not all birds start laying at the same age, some are 5 months some are 8 months.Well I'm hoping at least one of my bcm is a pullet the other is deffinently a roo lol crowing like crazy. Getting his tail feathers to his cobm is so big lol. The other isn't so much and dost crow so I'm really hoping pullet. I don't know yet though since there r no eggs yet there both 7 months old. I'm getting frusterated though caise I haven't had one egg yet. Even my bo isn't producing and she's 5 months. Extremely loosing my patience. Any tips to get these birds to lay eggs. Freerange all day but I follow them around and no eggs. How can u tell is there a sign when they ley eggs
