Hi! I have 3 younger ducks, 9, 11, and 13 weeks respectively and 3 new ducks that lay and are 18 months. Do I need to separate them every time I feed them? I got laying pellets and grower but I'll be out of town for a week and not sure my duck sitter will be able to keep track of which one eat what. They forage all day together and separating them is quite the task and workout, lol. Could I have my duck sitter just feed them one of those food for the week I'm gone? If so, does it matter if it's the grower or the laying pellets? Thanks in advance!
