I am new to this group. I was hoping to learn about free flight

["Remsh, Janet MS" <remshj@...>]

I have 3 CAG's ages 12+ to 4 yrs old. I don't understand how to get them to
fly to me. I have 2 of them flying to the play perch in the house, but how
do I get them to return to me? They are fully feathered. We dont go
outside but would like to train them to come to me just in case...
