heh, i've been hiding my cockerels in the house since my neighbor had heard the new roo i bought a week and a half ago. i found a better home for that loud one but i've been hiding my silkie Xs in the basement and my bantam polish hasn't started crowing yet but i'm keeping him in in the house as a pet. (all are about 3 months old) he makes a slight screech noise that i don't mind.
they get outside when i go out to do yard work and they stick close by but i have yet to hear either the polish or the silkieX crow out there.
the silkie Xs only seem to crow when i turn the basement light on to go outside with my dog in the mornings (we have a walkout basement).
i figure that a rooster/cockerel crows about as loud as any parrot/conure so why not keep one as a pet inside? my husband never even heard the full sized roo though 2 floors, i did!
