I would love to hear more about the experience when you can! I came very close to booking the penguin feeding some years ago but at the last minute we didn't, so still have some curiosity.
I know it's been quite some time since I posted this, but I haven't forgotten about replying!Life has been so busy lately ... Before I start, I'm not sure how to link it but on my profile I uploaded a small collection of photos from the experience if you wish to take a look.
The experience started in the penguin meeting area (the room with benches) and we were provided boots and gloves. No cameras are allowed in this experience, mostly because people have dropped their belongings on accident in the exhibit. The experience is limited to two people at the most, but individual experiences are possible too, if you wanted to go solo. Our friend joined us for the trip that day and waited at the viewing area for the exhibit to take pictures of us from behind the glass. Two employees explained what we would be doing while also sharing some information about the penguins here at the zoo. They also talked about the different kinds of fish we would be giving them, and how some were picky about what fish they preferred.
We were lead into a back room corridor for staff only, it more or less was just a walkway to maybe one or two back areas, one of them being the room behind the exhibit. There were lots of water pumps, machinery, valves, and other essential equipment for aquatic exhibits. The staff took a giant bait and tackle box from a freezer and led us into the exhibit.
Walking into the exhibit is a bit treacherous but it's also not a long walk. It's hard to keep your balance at first because you're walking on rocks but the area to stand is very small, so it was equivalent to walking a few feet in front of you. If you have trouble walking or balancing then this might be difficult for you unless you have someone else with you to help assist. That or I'm sure one of the employees would be glad to help you.
Setting down the tackle box, one of the employees gave us both circular trays and packed them with handfuls of fish periodically. These fish were pre-gutted and frozen to preserve them before the experience, but they were mostly thawed when we received them, so they were fresh for the penguins. I cannot recall every type of fish, but I remember smelt being one of them, as a good portion of them were not fans. The penguins definitely know when feeding time is, because they'll all gather in a group in front of you, waiting for you to feed them. Some of them were molting, as seen in the pictures I posted. We were told to hold the fish with the head facing you to minimize getting poked by beaks. We were also warned about a specific penguin, Empanada. She likes to stand very close to the feeder, sometimes behind them, and peck at their boots and legs until she gets fish. This time, I was her target, but thankfully she was actually pretty polite to me. She stood behind me, but my boots were as long as my shins (I'm the shorter one with grey shorts in the photos, lol) so the very few times she poked me, it didn't hurt because she was hitting mostly boot. I made sure to give her a few fish every couple minutes for her good behavior.

You can see her in one of the pictures I posted, she sat on a jutted out rock fixture to my left that was molded into the wall.
The penguins all have zip-tie armbands on their flipper. We were told the ones with matching colors are a mated pair. There was a couple in particular with orange bands that stayed for the entire feeding. They're also visible in the photos. The penguins weren't the only ones who wanted fish-- the free flying birds in the exhibit also kept an eye on us. One even flew at my boyfriend, perched onto his tray of fish, and quickly took one before flying off. We actually got a picture of it happening, but I didn't upload it here.
All in all, it was a great time! I would do it again! The staff take very good care of the penguins and it shows.
