I'm looking at getting a small herd of cattle for the first time. I have had sheep, but don't have much experience with cattle and I'm not sure what to look for in purchasing animals. I have read some places that recommend getting animals 6-12 months old and avoiding bottle calves or very young animals. I'd like some tips on what things to look at to determine healthy cattle, and also what I could look for in terms of a productive beef animal. Any advice would be appreciated. Thanks!
