our 4 hang out with the hens/ducks/ponies all day, don't try to fly or leave our fields, though they could get through the hedge if they wished.
at night they are in a fully enclosed safe area with a small shelter, which they do use a little. they are fed mixed poultry grains with the hens morning and night.
they come in easily, i just point where i want them to go and they go, or if i want them in early i shout 'ducky ducky duckies' and they come.
