Eye pecking?!

[JJpuck]

Hi everyone! This morning I received two beautiful babies (1 pekin and 1 duclair)

. They seem healthy and energetic. However, one of the ducklings (who is named Bean) keeps on pecking the other's (Petal's) eye. Whenever Bean does this to Petal she peeps really loudly and I think it's hurting her. Should I be worried? How do I stop this? All answers/suggestions are welcome!

They peck at shiny things. Supply other distractions. Also, it probably does hurt.
