Are 2 yellow chicks are 13 days old and are pecking at the other chicks feathers they don’t do this to the brown chicks just the other yellow one. We put a brick under their food and water so it’s elevated and our biggest chick- the yellow one is standing on the brick under the water and jumping onto the edge of the bucket/ coop and then jumping out of the bucket/ coop!!
