BMD....,
I've had Buffs prior to my latest batch and they laid nice xLarge eggs and they laid well. My Buffs are the best mothers and I've used them 2 years in a row to hatch eggs. - They are good at hatching and keeping their chicks safe from the other hens.
I purchased 6 Buffs, 6 Black stars and 3 EEs this spring, they are currently 33 weeks old. They were slow to lay and out of 16 hens, I've just started to get 10 a day (ok so it's winter here, but it's the best they've done so far). Their eggs have been large, at best.. normally they are medium size. The EEs are producing the biggest eggs of the bunch. I'm not sure what is going on.. perhaps when spring rolls around their eggs will get larger.
How have your hens done this summer?
