I have 2 flocks of chickens. One flock was hatched in August and the other was hatched in October. The older flock consists of 9 chickens (at least 1 EE rooster), 2 Wyandottes, 2 Cochins,2 Brahmas and 3 EE's. The younger flock is 3 Jersey Giants and 2 Silkies. The older flock has been in the coop for about 2 months. I have built an enclosure inside the coop for the small ones to be in, but would like them to mingle with the others and not be in such a confined space. I have read online to keep them separated until they are the same size, but how do I do that with Silkies that will never be the same size? The Jerseys are almost as large as my 2 EE hens, but smaller than the rest. They still sound like babies (the younger flock). I did try letting them mingle once, but 2 of the hens cornered them inside the coop. Should I build a separate run for them or should I wait until they are older (16+ weeks?). Just breaks my heart to keep them confined in a small space and not let them be outside in the run with the bigger ones. Want to do what is best for them. Thank you for any advice.
