Hey Zam, no worries about them. Yes they need to eat but try this. With the rat pinks, a lot of times they don't move enough to catch the snakes attention so I bump it up to the next size which is fuzzy rats. They still have their eyes close and I leave them in all night and check the next morning. If that does not work, a hopper mouse 99% of the time will do the trick. Again, leave it in all night and don't bother the baby at all.
