I have about 50lbs of Roudybusy Small and I tend to leave them out until they eat almost all of it. They turn dusty. I sometimes switch it up as I have a lesser quantity of "Breeder pellets," and I have 25lbs of seeds from a company that came from Canada and the seeds are from Canada. 25lbs bag about 24lbs are left. Amazon jacks up the price when they see you ordering so I wait until the price is low, this stuff costs.
I try to give them seeds once or twice a week. They also sometimes get broccoli.
I give fresh seeds and pellets each day and only put enough in the cage for the day. If you leave it out for too long it goes stale and the birds wonít eat it. By only feeding enough for each day, itís much easier to see how much your birds are eating and therefore get onto potential problems quickly.
