Medicated feed won't treat coccidiosis; the dose isn't high enough. For treatment you need Coxoid.
Treats. I use one of these, without the bowl. The platform the bowl sits on is held in by screws, which I unscrewed in order to pad the platform with some cloth. The first time you try it, you'll need to make it easy to get onto the platform. Find a way of making it touch the edges of the solid surface they'll be stepping off from, so that their foot comes straight down onto the platform.
I'll try picking each up, feeling crop, and weighing (um. Tips for weighing, pls?!)
