First
Very sorry to hear of your family loss.
I keep pigeons also, but currently do not have any due to a predator raccoon entering my loft in the autumn. Sure do miss them. I will restart my pigeons this spring.
I also would let my pigeons free range fly, and they would go back into loft at dusk. Sometimes sooner. Here is a way to train them.
Let them out hungry. That would mean that you would have to, not have feed inside available all the time. After they fly around a while you would signal to them that it is dinner time.
Here is how you train them.
Start by feeding them inside loft and making a juggling sound with a coffee can filled with nails. ( About 20 so they make a racketing sound. ) Pigeons will associate the sound with food service. After a few days, let them out hungry ,,, Then about an hour later place food inside loft and shake the can, so the pigeons can hear sound. They will hear sound and rush back into loft. There are a number of You Tube videos that demonstrates just how its done. I can find them and post links to them If you would like.
Ask anything else you would like info about. I do know pigeons quite well. You can see some of these pix in my albums.
WISHING YOU THE BEST.
