Hi I have 4 Buff Orpingtons that are still maturing. I got the Orpingtons after doing research and deciding they were the best overall bird for me to breed. However, I was just looking at the reviews and many people say that their egg production is only so-so for the amount of food they eat. How many eggs do you get from your buff Orpingtons? What other heritage breeds that are dual purpose and eat less are there? Oh and they need to have large white eggs because I will need to be able to tell them apart from the Buff eggs when its time to hatch under a broody hen.
