I guess Im not totally sure on growing time...I just kinda go by mowing season here

we're about 45 miles north of where we will be eventually, but we usually mow til the end of September and then leave it until about late march. it doesnt get too cold here and we dont 'normally' get much snow.... but its really anybodys guess.
I have no idea how to figure these things...I just dont want to get caught off guard.
With the round bales, couldnt you just clip the wires and haul what you need out to the pasture with a Gator or 4 wheeler? and then keep the rest in the barn where its safe and dry?
we have plenty of working hands, so the chores arent that big of a deal for us....the kids will think its 'fun' for the first few years at least! LOL
They still love feeding the chickens, of course that is a lot of fun.
We have about 35 chickens now, and go through about 200lbs of chicken feed a month.
Thanks for the input...I'll keep thinking on this and taking notes
