My duck is about a month old we have been feeding it a mixture of raisons, half a smashed bannana, smashed boiled egg,and oatmeal with water added. We have been keeping it outside for a little while when we are to get him familiarized with our property. Are we able to let him out full time by now. Also do we have to feed him the mixture every morning and night or just once or is it optional? We were home over the weekend and we left him outside by him self. He stayed the chicks he has grown up with. Any advise would help.
