Now, however, there are tags [tag:animals] [tag:pets] and [tag:chickens].  To disagree with [@Grace](https://sustainability.meta.stackexchange.com/users/17/grace-note)'s conclusion - it seems that most uses of *animals* is in the livestock sense.  I think that animals is too generic to be useful, because it would include *pests*, *predators*, and *pets*.  Perhaps you can keep something like an ecosystem tag, **remove the animals tag**, **add** *livestock* and **disallow** *species* tags.

It seems to me that if you are getting too many breed-specific questions, that those will probably have to migrate to something like the proposed [Agriculture SE](http://area51.stackexchange.com/proposals/68528/agriculture).
