Thank you everybody for the advice
the hams will come and sniff my hand, but they won't take treats. I'm starting to think maybe they don't like the treats? I mainly use the Oxbow simple rewards banana treats (only a small piece though). They were eating them before but now they don't seem to take interest in them. I've tried millet too but they don't seem to want that either, though they will eat it if it is just in the cage. I've also tried picking out their favorite bits from their food mix to see if they want those but no luck. Any treats that you all recommend? I've heard fresh veggies are a good treat option and i may try those. I wanted to use pumpkin/sunflower seeds but both of those are in their food mix and they don't seem to want them when they are on my hand. I've heard some hams like mealworms but it'll be awhile before I go to the petstore to get some. So is it the treats that they don't like or do they just not feel comfortable with my hand?
