budgies help please=(?

  My mom has 12 noisy budgies at her house and she's not there today i was wondering if budgies do eventually sleep when they're tired or do i have to get over there to put a blanket over them?
You can put a blanket over them now but ONLY FOR A LITTLE BIT so that they'll quiet down if you want. An hour tops.



But at night you definitely cover them up so they can sleep and feel safe. It also protects from cool drafts.
You have to pull a blanket over them at night so they can sleep and also so they don't get cold.
I'm not a budgie, so cant help
