Any, who don't, If you don't mind my asking. Why?
So far, I've done a little of it. Not enough to know if I want to keep doing it.
Too much daily work making the feed and washing dishes plus the risk of throwing out money if it spoils.
Spoilage always being a risk fpr anything in this hot, humid climate.
I prefer a setup where I can go a couple days with minimal attendance if I am working long hours or am having physical problems.
