Does anyone know of anything I can add to "extend" my duck's pelleted layer feed? They have access to roughly one acre of pasture. BUT they choose to sit at the feeder and chow down. They aren't free-ranging as much as I'd like. I'd like to be able to leave out something but I want it to be a protein supplement, not their entire diet. Could I do oats or another grain? I dare not put in cracked corn! They would eat themselves to a heavenly death, lol. I have geese out there too - again not really grazing like they should be. We did just move and pasture is new to them, will it just take time to adjust? Do I keep free-feeding layer pellets or cut it out altogether to encourage them to forage?
