General Multiple piggies tips

[Fabricio Yui]

Hi everyone. i have made 2 cages for my piggies(3 girls and 3 boys) from some kinds of wood boards i have. like this:


working with furniture had a positive outcome. haha lol

i have another one of those for the males on another room, but i want to know a couple of things, the females have 7 months,
6 of which they live in this house, they do come play when i'm around, ask for treats, but to this day i still haven't figured out
how to make them like being touched. I am around them every 2-3 hours to change the things, and give them some treats or something,
but since i have the 3 males on another cage like this i don't have time to pick each of the 6 and play with them everyday. So i wanted to know
how to make them let me touch them more, not that i want that they let me pick them up, i just want them to get closer to me.

The mother of the 6 recently died, had her for 11 years, and she didn't mind me touching her, at all.
Sorry if what i said didn't make much sense, i would love to read any help you guys might have to share.
