I just switched to a bag of pellets for my 3 girls this week.The crumbles were all over the floor.
I found the feeder buried under pine shavings yesterday,and it was still pretty much full. I threw some outside for them,but they did not eat them. I gave in and added some warm water to the pellets in a bowl,and once a warm mush they ate it up.
I am still going to give the pellets,but will move the feeder to higher ground on a cement block so they don't bury it.
Like others said hopefully they will eat the pellets when hungry.The grasshoppers they eat are way bigger even when the 3 tear them to pieces trying to get a chunk.
I also bought some bags of whole oats,flax seed,and cracked corn to give once in a while. I figure I can throw some oats and flax seed to grow in the yard next spring too!
