Two seemingly healthy roosters dead within two days of eachother

Just a FYI: Feather Fixer has a lot of calcium in it.
I stopped using it because I have roosters and young birds.
Also, I use two types of feeders (one galvanized metal and one plastic) and I can’t fill them up all the way or my birds scatter a ton of it.
I fill them about 1/3 full and they don’t end up with as much on the ground.

It's super important to store feed in a dry place, in a container where it can't get damp or be touched by rodents, and where it does not overheat.

Another thing a lot of people don't realize is that, if you use galvanized cans - like a lot of us have to just to keep the mice out of it - you need to leave your feed in its' original bag. Galvanized cans can contaminate your feed. To get around that, you can put a plastic can inside it for a liner - but that's not always an easy fit. The bags work just as well, and you can store several types of feed (and grit) in the same can.

OMG! Really? Are you certain about that? I need to rethink my feed stoarage!

I am not surprised by this, but would like to know where this information comes from.

Since some chicken feeders are made of galvanized metal, I question this information. I do know that one should not use metal to mix or serve fermented feed b/c of the moisture and extra acidity created by the SCOBY.

I would be interested to know how you feed them. If you mix scratch into their feed they will bill the feed out to find and eat the scratch. This not only causes a dietary imbalance because they eat too much scratch but also increases the risk with wastage going mouldy and attracting rats. There is no spillage under my hanging feeders using pellets unless a chicken flew into it for some reason and then I immediately remove the feeder until they clean everything up off the ground.

You did not mention how old these roosters were as far as I can see? It could be Marek's since they are breeds that are prone to it and you found one with wings outstretched. The visceral type can cause sudden death.
