Newbie here! Call duckling questions

[bobsmith2002]

I recently acquired two call ducklings from my local feed store today that were hatched on May 20th. I am keeping them indoors inside a small rabbit cage and I am using paper pelleted bedding. I noticed that they are eating the paper pelleted bedding. Is this normal? Will they eventually stop doing this and go back to eating their food instead?

Also, is it normal for them to scream when I leave the room? It seems they like my company.

Sorry for all these questions but my feed store charged $75 for each of the call ducklings, and I don't want them to die.
