There is unfortunately a lot of misinformation about hamsters living in pairs, while it is possible a pair of same sex siblings may live together successfully it is extremely rare.
The vast majority of pairs will fall out as they begin to mature & need their own territory, keeping them together can be extremely stressful for them which damages their health in itself & injuries, even death, & lack of food for the more submissive one are all the most likely outcome if they aren’’t separated at an early enough age.
Because of the stress it can cause them the wait & see approach isn’t fair on them.
