I have a sweet little Golden Sex Link that "grooms" her EE brooder mate's beard and muff by pulling the feathers. They are 1 1/2 yrs. old now but the habit started when they were chicks. She doesn't peck on any of the other birds feathers and only gets the EE's if they are on the roost next to each other. My poor EE has a scraggly looking beard, that's for sure. Maybe Omelet thinks that those feathers are out of place and she needs to take care of them for Dini?!
