I was told by breeder that his barbs had some homing ability to point theyd try to get home when sold and let out to soon. so id air on the side of caution and settle them in first inside for week to month, then settle to surroundings outside. the rollers id say youd be fine inside and out after a week, but told some lines have some homer in for vigor, the larger showier ones. ive had one hen, when first back into pigeons, that when let out finally, took the cock and two squeakers straight back in direction of were seller was. recently a show and performer winner hen, I traded for, did the exact same thing. ive never had this trouble with any other than the largest showier roller hens, so maybe they just retained more homer blood and had stronger instinct to get back to old nests, and i had them nesting but didnt wait for them to have raised any young for me. both were younger birds. those two id had kept penned up one for month and other recent for several months, then finally decided to gamble on them as felt bad for not letting them out to fly with rest. non of my cheaper smaller strictly performing birds ever had that problems in between, and all others were let out after week only and homed then rehomed to new places, and have moved three times since getting these that have had now since got back into pigeons, and got into rollers. I used to be strictly a homer man, and saw signs of homer traits, but figured good looking roller abilities showed enough dilution of homer blood, but guess was wrong.
