I have kept tame muntjac in a three quarter acre pen for the last number of years. They have done well but need regular supplimentary feeding every couple of days with a mixture of concentrates mainly consisting of calf pellets. A great deal of the food is lost to rats, and it has become a bit of a chore. I would like to rig up a peck feeder on legs similar to that used for feeding pheasants. Does anyone on here know where I could source a large size pan feeder attachment for the bottom of the barrel and would it work with pellets like they do with wheat. These are standard calf nut pellets of about 1.5cm. I would be happy to get some made up somewhere if there is nothing available as standard. Is there a rat proof concentrate feeding station for lambs by any chance?

Thanks in advance
