I have a mallard drake (clipped wing), a brown indian runner hen, and a splash cuyuga hen. We let them out everyday before my mom goes to work and then when we come home they are always in the yard. My mom said that they have been coming up front and we have a lake accross the dirt street and then there are houses then the lake, my mom looked twice but didnt see anything. There is no sign of an animal taking them no feathers or anything and i would think that something could take all three expecially the mallard without him putting up a fight for himself and his girls because he is very protective of them. Were they usually stay for the day there are alot of wood behind the coop, would they just walk away in there? I think someone could have seen them and just stole them cuz there are alot of idiots nowadays. I just really hope there safe cuz i am sooo upset right now. I think i might make up a flier to give to a whole bunch of people on are street also.
