I free flew all my breeds of pigeons and birds when did rescue, and these breeds did best staying close when not foraging n or flying. Some breeds seeming n maybe strains i had only of, were high strung taking off at slightest thing.
Capuchines (better parent than even parlors flights, rollers and homers, all in order down) seemed to be the silkies of the pigeon breeds. Next would be tumblers and/or rollers.. I've seen great exception s though.
Jacobins seemed especially stressed by anything and everything, even when I trimmed their head dresses. I looove pigeons but now stick to performance n flying breeds (unless came across fantasy called breed), and mostly rollers as they are easiest keepers. Many to most love flying their Birmingham rollers, but find them B.O.P. (birds of prey) magnets. Only show type and white homers seem to get taken from me though (its still a fear though), and all taken only one or two so far each, as my Muscovy ducks chase falxans etc away (drakes kill if catch), course scovys attack snakes rats etc cats etc vermin here too (they'll eat any pred/pest they can tear up and swallow). Housing birds best used inch hardware cloth on front of box coop to cages all around and under, as that'll save you trouble on long run as everything else press n pest can get into. When breeding give two nests per female, as that'll solve most probs from nesting n rearing young as otherwise stagger nesting pigeons do, could show probs from.. when young about two weeks, female wants another nest to lay again, and male mainly takes care of young till next eggs hatch and again are about two week olds.. So on n so on, that an at least three feet square cage accommodates (most commercial breeders save space using use two foot square cages and have bad staggered raising results burning out breeders).
