I think the biggest thing to consider is the knowledge that one has on whatever livestock they're interested in. Too many are getting animals without learning about them first. I realize we all have to start somewhere but, getting chickens without knowing they need, for example, chicken feed, is just silly. And yes, this is something that does happen... omg. Or, without knowing they don't produce milk??? Hahaha I have seen this on FB... It's just... omg. Hahah.

Great points made!! Also consider how much work you want to do. Right now, we're sticking with birds. Very easy to take care of them all! They all eat the same food and require nearly the same things!
