Hello, I tried to introduce my 4 baby hens to my flock of 1 rooster and 4 hens. I let the new ones out and the rooster came running toward them. Not sure if he is going to be mean or not. The babies just started squeaking and running from him. He was chasing them. The hens did not come to see wha was going on. They were jus out in the yard. The baby hens are 10 weeks. Should I wait or try putting them in the run together? Any suggestions would be appreciated. Thank you
