it looks like it would make a good teal pond , i would put some barley in like you have done but spred it over 20 to 30 yards along the waters edage, some in some out the water , it would pay best to put 2to 3 decoys in there antil the ducks start useing it , just keep your eye on it if you can daily, when the barley starts going then put more in but dont over feed it , the more you put in the more they will eat, ducks are very greedy , i only put 1 full bucket in each day and that is feeding up to 150 mallard plus 50 to 60 teal but that is fed every day without fail ..
