All of this talk about jury duty makes me wish I could say that I hadn't bee so dang close to the events of the Polly Klaus kidnapping.
1 - Her mother was my boss when it happened.
2 - I was driving home from Cloverdale when I saw a bunch of police cars and officers on the side of the freeway...
I use dollar store baskets or small cardboard boxes. I cut the entrances into those.
You could cover the cage so it stays dark until you get up.
I'm guessing that you were told something like 3 birds per square foot. That is what commercial breeders use for space requirements, but to my...
The cage sounds small. You want at least 1 square foot per bird after you've subtracted the space used by feeders, waterers, sand bath, and hiding places. Your hiding places should have two entrance/exits so that your birds can't be trapped inside by an aggressor.

How much space is their pen?
Do they have enough hiding places?

Since you're in a dorm, let the dorm manager know. They'll turn the water off to your toilet (There's usually a little knob to turn below the tank behind the toilet) and should fix it for you.
There's something going on. It's not unusual to lose a couple, but you are losing far more than that.
What is the temperature on the ground under the heat plates?
Slow leak. It should be an easy fix. Probably just the little rubber seal inside the tank. The one that opens when you flush, then drops to seal the tank to let it refill.
There are not feather sexable by chest patterns. They might be sexable by facial patterns, but that will have to wait until their heads are fully feathered in.
