Well, it may be worng what i did. But i treated them like my pets, the babies were born in the basement house..basically living with me. A club member who gave me the female racing pigeons told me that once they learn to eat which is in about 1 month, he separates them from their family and grown up birds in a separate loft with aviary, he keeps them for 2 -3 weeks in the daytime in the aviary to get used with seeing the surroundings ,then leave the trap open; he said than at the begining they come out and wonder in his yard and one of the days they take off flying around the house for a few minutes. After that they are ready to be taken to fly from different miles, of course first short distance then longer. Take into account my friend has racing pigeons whom instinct of returning home is in their gene. My must had roller genes and i read that there is a different way for training them. They cannot fly too many miles and usualy the owner has a portable kit from which they can be released from different places and come back to the kit, not home.
