I cant add any further suggestions about how to get them home again...But I would love to see video of some of your efforts...Im sure it would make for some entertaining watching. I did just want to say...I know its obvious.. But if you do mange to catch them again- dont forget to clip the wing feathers so they dont fly off again.
.The problem is is that they look in so good condition I dont know if they will go after the bread Im gona keep trying and hopefully once all the grass and bugs die they will get hungry enough to eat some.
