For my birthday, my grandparents got me 3 new hens! I was so excited to add to my flock, especially since we lost so many chicks to predators and spent a lot of time (and money) securing our new coop. We brought in the new hens at night so they could roost with our old chickens, which included an Americana and a Silkie (who is a rooster, which we couldn't of known since they can't be sexed). The 3 new hens consist of 2 Americanas and a Leghorn. The Leghorn is a month shy of laying while the other two Americanas are currently laying (along with our original Americana). For some reason, the rooster and our original Americana have accepted the two new Americanas and not the Leghorn. They chase the Leghorn around to the point that she is so skittish and standoffish. She keeps up high in the coop so they can't get her. I'm becoming worried. When I went out this morning, I had to stand guard just so the Leghorn could eat/drink without getting chased. What in the world can I do? My chickens are my world. I don't want to give up a chicken because the others are being jerks. I really need help with this!!!
