I bought 3 ducklings to add to my duck flock. At the same time, I bought a Wyandotte chick bc I had previously been unable to find this breed in my area. Now that the ducks have joined the others on the pond, the young pullet is unhappy in my chicken coop. At first I let her free range with the others during the day and then put her up separate at night (to prevent the other chickens picking on her). Then I put her in the coop at night. She hasn't really been hanging with the others. Also - when I let them out to free range- if she sees the ducks- she races to them. She will follow them all the way to the pond and just stay there while they swim, etc. recommendations?
