I call "her" Opal, born 3/18 can anyone tell if she's a pullet or roo? She's my first silkie! I also have a flock of 7 hens, I've been letting opal out in the yard while I'm outside and call the girls over so they get used to seeing her around. Is there anything else i can do to make integrating them easier when she's ready to go in the coop? Thank you!
