I have a mixed flock of 4 buff orpingtons, 1 rhode island red, 3 silver laced wyndottes, and 2 golden laced wyndottes. These girls are three years old and have been together since they were day old chicks. They are becoming inconsistent with their laying and so I feel it is time to add to the flock. I do allow them to free range and when not free ranging their pen is on the large side (22 x 25). My question is what breeds would be good to add with this flock and how do you add them without the new ones being pecked to death(my Wynddottes and Rhode Island red are bullies) ? I want to add at lease six to ten more hens. I would add all buffs but the ones I have go broody quite a bit and I hate having to put them in the broody box to break them. I would like to add hens that are people friendly and fairly good layers of brown eggs. Any suggestions or advice would be much appreciated.
