You can raise beef and dairy cattle together - they don't know they're different, lol. And, you can do 100% grass fed in NY; I know someone who does. You don't have to be able to graze year-round, just be able to provide enough good hay during the winter and any possible droughts. (I'm in WV - we DO have winter!)
100 acres is a lot of fencing for an 'all at once' job - that's three or four straight weeks of fence work = painful! You can easily do electric on step-in posts for rotation paddocks, but you're going to need a good perimeter fence - unless that's already in place?
You can look up the farm at Sarver Heritage Farm dot com (without spaces) or find it on FB; I can be reached much more reliably at either of those than on BYC. While I don't hang out online a lot, those are daily check-ins; BYC is more of a random stop during hatching seasons ,
[/quote the fencing will be one paddock at a time. There are currently 3 paddock that are fenced with electric already. Each is 3-5 acres. Its nice thick green from about mid April until the first bad snow. Plus I can use the unfenced to grow for winter. There is water to each paddock and a run in. So I could start this year on cattle as long as I can convince my husband.
As for the extra year I have to wait for grow out, no big deal. Healthy is worth waiting for. I grew up in Texas so grass fed is my preference.
