Baby Hamster Smaller Than The Rest And Crusted Eye.. What's Wrong?

Well im not sure but i would take it to the vet, it cold be sick.

The smaller ones of the litter are called the "runts". My hamster gave birth to nine and two are noticeably smaller than the rest.  It's okay though. Just watch them when they are being nursed and see if the smaller one gets on the mother's teet. If not, pick a bigger one up off of the mother and place it near the solid food. Then put the "runt" on the mother. That should help but be careful. If the mother shows any sign of being upset or annoyed, stop whatever you're doing immediately.
