I love my mixed flock. You could always just decide on one breed roosters or swap them out when you want to breed so you still are breeding purebred on occasion. I find it was to manage the roosters while all my hens get combined.My latest YouTube for those who are not subscribed. I really need to decide on something at some point, Barred Rocks or Brahmas if I keep only one breed-there may a few hens not the same breed as the rooster, but generally, one breed-or, just go back to a fun mixed flock of whatever, different breeds and crosses. There are pros and cons of each main breed I own, but for ease of management in the future, i.e., free range time for all at once except maybe the truly crippled ones like Neela and Panda who cannot handle rooster-love.
***Maretta is really going into Day 20 already. I set the eggs on Jan 5 in the afternoon so counted the next day as Day One, but going by the exact timing, she's already in Day 20.
