Denny I'm sure many will offer advice . If your concerned you lost all the old birds won't you be better retaining this years young birds as your future stock ??? Racing is over but if wanting to train pick your days , your young birds must be ranging freely before training , then train in 5 mile increments i.e 5 mile , 10 mile , 15 mile , 20 mile , if get a bad toss at any stage take them back to a previous lesser training spot to regain there confidence , then move them on in 10 mile increments , 30 mile 40 mile 50 mile after 50 mile return to small tosses of about 20 miles , your young birds would be ready to race
