Avna gives good insight...
So, hopefully I can help with the food issue.
Much of where to buy your feed will be determined by what area you are and what manufacturers are in your area.
Hay, Wisconsin is loaded with hay suppliers of many varieties grown...
Much depends again on proximity to you and more importantly how big and where you intend to store your hay.
Square bales or round rolls...how many are you wanting to purchase at a time, how are you going to transport it and if you do rounds how are you going to move them.
For rounds, I would strongly suggest a tractor with hay forks to make your life easier and then you can do it without needing to ask/rely on others cause when you need hay you need it now...not later.
If you do large rounds there can be a lot of waste or not much waste depending upon your set-up and how you manage your horses eating habits.
So, here is just one place for a reference of places that sell small squares, round rolls large, how many are available, delivery option or not and if there are minimums to how much you must purchase...biggest though is it is also by geographic location. Wisconsin Hay For Sale
With the use of cell phones, you can't
go just by area code. I know friends who have California area codes and live in the Carolina's and a Alaska area code and lives in New Mexico so read those ads carefully.
There are many places that advertise hay and feed on local Facebook groups, specific hay sale sites, feed sites..
If you use or see any local publications there are often ads for local farms...
Craigslist is another in the Farm & Garden section.
You will also meet people who own horses in the area who could probably head you in the right direction with suggestions.
You can find farrier and vet by that means too...
If you have not moved yet, if me my animals would be vaccinated for any issues in that locale prior to the trip and farrier would be doing hooves the week of the move so you have a couple weeks to locate new professionals before it is uh-oh time and you have to take whatever you can get..not always good.
