not at first as the gray was in brooder with chicks and played momma to them, it didn't want to accept the new baby, until it realized that the new baby was only one that enjoyed going swimming with it. worked well as one of the pullets took care and defended the little guy until the gray and him became best of buds now. And they got a whole pond to themselves lol, was really good for helping break the bond of the gray duckling and the chicks too, no more stress to go swimming cause the chicks are all crying.
