I have a Welsummer pullet that I got in a batch of 8 and raised from day olds. Recently the one pullet has been looking thin and dull. I brought her inside for a few weeks to gain some weight. She eats, drinks, and seems fine inside. I took her back outside since we had a warm spell. I put her back in the coup at night when the others were already asleep. I have used the "wake up together" method with great success in the past. But this little pullet simply cowers in the corner and tries to dig a hole. Can a chicken be afraid of other chickens? She doesn't eat or drink outside, and she just cowers and hides.
