@emma duck lover I can only tell you what works well for me. I feed mine at night as it gets them into their coop easier. My goal is to feed enough that their is some left in the morning. They will forage and munch on the leftover feed throughout the day. It is usually gone by lunch time which works out well so that they are ready to come into the coop to eat at night. If I have too much feed down they don't get excited to coop up at night and can be a little naughty when we herd them in.
