I have 3 pekins that Ive had since ducklings....and moved them from California all the way to South Carolina! On our property we built a 2500 sq foot poultry yard and also bought 10 pullets and one rooster! Theres a coop in the poultry yard... a lil pool and an open nesting box made from a door frame with roofing over it for shelter for the ducks. So since having my new chickens and ducks all in the yard together... its like Im the referee trying to keep the bullys on theyre own side of the playground ...and the ducks are the bullys! When im in the poultry yard , my chickens run to me and hang out around me foraging. But when I leave the yard... the ducks chase all the chickens under neath the coop and guard the area not letting them out!! Any one have advice or input on what i can do ? I cant just hang out in the poultry yard all day!!!
