I have 4 BOs, 2 Autralorps, and 5 young barnyard mixes and 1 rooster. I love my flock, but we are worried that the BOs (over 2 years old), might be getting too old to give us much of an egg supply. Since half of our flock is older and half is younger, we want to get some new chicks to keep our flock young, laying and molting at different times of the year. Our current coup is about 32 square feet with 3 nesting boxes. I know I will need to completely renovate and add room if I want to expand the flock. I love my hens too much to knowingly eat them. Should I sell them to make room for others? Any other advice or stories of what you do with your aging flock? Thank you!
