I have 2 hatchlings a few weeks apart but brand new, the smaller one doesn't seem to have an appetite at all.. The bigger one has been interested mostly in clovers and green leaf lettuce but at least eats. Any suggestions? Thanks!
Do you have the separated? If not, the bigger one may be bullying the littler one. Separate them for a few days and see if the little one will eat. Or at least feed the little one in an area that he can't see the big one and the big one can't get to the little one. If the little one eats, then separated them. It also could be just getting settled in. However, usually sullys need to be housed alone.
Along with the info provided, when introducing new things, some can be super stubborn. You can chop up the new stuff finely and mix it into the preferred greens. Slowly, you should add more and more new things. Separating may be advisable though, you don't want to take any chances as cute as it is to keep two little ones together.
