I use something called Phase 6. I keep their feed full, but I noticed that when my birds eat it they leave behind the finer particles. Not only do they leave it behind they knock it out of the feeder onto the ground and just walk all over it. I never see them pecking at it, as they do the scratch that I throw down once a day. I know that the Phase 6 is formulated for the best nutritional balance for my birds, so I was wondering by not eating the finer particles are they missing out on something that they need. I don't know what the finer particles are,so I don't know what they are not getting. Any ideas???
