First I 100% agree with anyone saying don't barrow. I personally lost 80%+ of my herd the first year(out of 40 does/75 fawns) to ehd, that was about 4 years ago and am still working at getting back to where I believe I should be. In hind sight. I believe that a person could develop a relationship with another rancher or work a deal to where you could purchase a number of does that you could afford with this in mind...... Buy bred does that can be left at current ranch until fawned out and re-bred. Then bring those bred does and fawns home. It will cost purchase price, boarding for a year, and breeding(live breed). This would allow you to have more time to build a pen, buy a dart gun and meds, some winter hay and some misc things. some of these deer may die in the mean time at no fault of the seller, arraignments need to be made prior to purchase. A contract is a must. As others have said.... You don't need top 30 deer to produce like the top 30.... Look over many pedigrees and any production records that are available..... Buy does that have produced stockers at two..... It can be difficult enough keep fawns alive let alone keep a deer alive for 3-4 years till its big enough to shoot. Find out where your preserves are and find out what kind of bucks they shoot the most of... Raise that kind of buck.... More than like a mostly typical 160-200" rack. Aim for the higher end as it cost as much to raise a 160" as it does a 200"..... The genetics are available to do all the above at a reasonable price. Just look around a lot.
If you are able to find a ranch willing to work with you on a scenario like above from the time deer hit your farm you should be able to sell bucks in about 24 months. In the mean time watch your input costs and make sure that you only spend what you have to..... Also keep in mind that you will have excess does eventually, there can be options if you are willing.... Personally I would keep the youngest, attempt to sell the oldest and if I had to I would butcher the oldest if I couldn't get a dime for them.... Put your business plan together based on not selling does, that way you can see true potential or lack there of depending on your input costs
