update
we cleaned the basin, i put the males in there as it seems to be less of them than females. https://youtu.be/1bpJ1Gw0Xvc
i'm not sure if the bottles are working. i did the neck scruff test thing and it's not too slow (fur goes back down in less than a second) but also not so fast as some videos show. i'm not sure if they're dehydrated or not, but i don't want to risk using water dishes because their desperation to flee the enclosure makes them step/fall inside the water.
i'm getting mentally exhausted as days go on. i had to sleep in the living room last night because the pups wouldn't let me sleep (i'm NOT a light-sleeper, when it was just quione doing her hamsterness it was fine)
i have commented about this with my girlfriend and she says that giving them to a petstore might be my only option, due to some factors: 1) adoption here in brazil is popular only with dogs and cats, hamsters are more looked for in petstores, hence why so many adoption posts did not get any answer; 2) i can't raise them all obviously as i don't have enough bins, money nor patience for caring for 7 hamsters total; 3) breeders are really hard to find, and the closest one i found seems to be one of those breeders who keep the animals in a bin with each other carelessly (and without anything for them to do) and 4) even if i found someone, or a breeder, an uber would be very expensive and my sister's boyfriend (who has a car) already said he will not take us anywhere too far due to the gasoline price (here it's an absurd cost).
speaking to my girlfriend kind of made me notice how tired i am. i'm doing my best for these pups but i don't think i'll be able to do anything more. my parents aren't so willing to help me, there's the factors i mentioned above and overall i'm not in a mentally good state to take care of them anymore. i did all i could. i'm still a child, after all.
yet the idea of giving them to a petstore that might give them a terrible life makes me feel like i'm an awful person.
still, i'll wait some time before making any decision, as i particularly hate when i make a decision and then realize it wasn't necessary.
thanks for all the support
