I like this plan.I'm just doing this to show folks how unlikely it is that it's the feed. There are too many variables. But folks seem certain that there's something different going on. So when the feed comes back with the same analysis as what's on the label (which is what I'm hearing is the biggest conspiracy atm), then at least that will have been examined. Maybe I'll send some of the other non-tsc stuff, too.
Rabbit owners know feed contaminants and recipe screw ups are actually pretty normal because rabbits just belly up and DIE from feed issues. Chickens are more resilient and the same level of problems could easily just stop them from laying.
The conspiracy theories without anyone bothering to get proof has irked me, though. If folks are convinced there's a problem with the feed, literally the first step is to get it analyzed so the entire batch can be pulled and the manufacturer held accountable and if the recipe is being intentionally fudged... clean it up.
