Please NEVER assume when it come to the husbandry of your animals.
Second....... Leave them alone for a while. You have had the albino 7 days and tried to feed it twice already? Stop. Breath. Wait 4 or 5 days and DO NOT handle them at all.
All you are doing is adding more stress to them.
After this time. You can try f/t and then IF it doesnt work try live hopper mice. They get the job done every time.
