well if you didnt quarantine right away it may be too late now as they have been exposed to each other and quarantine should happen the day they come into the house...better late than never tho i guess...some precaution is better than absolutely none...

and regarding using millet as a treat and the mess or whatever...it takes just as much effort to offer fresh veggies as a treat and that is also more beneficial and nutritional than millet which they get in their seeds anyway...and no time like right away to get them interested into fresh veggies...over millet...and no mess either...no risk of any of the hulls or dust getting into nares or any other kinds of complications...

fresh carrot leaf or beet leaf or parsley sprigs or brocolli head or snow pea pods..any of that.. lettuce has no nutritional value tho...even a bit of baby spinach once in awhile...anyyyyyything but millet...but thats my opinion and to each their own...ya do what ya gotta do ..lol

clearly im not a millet advocate but thats never been a secret in here...
