I am not even sure on that. They are a hybrid developed by a research farm in Canton, MN (Badgersett). My husband has wanted to get some for a couple of years. Chestnuts won't normally grow in a climate like Minnesota, but these were started about 25-years ago, I think, to be hybridized to be hardy enough to handle it here. There are other trees I would love to have here if they would grow in our zone, but I will have to settle with what we have.
This is the second summer of chicken owning. I have a large chicken pen, 800 square feet, that previously was an overgrown no-man's-land between the yard and pasture, with pine trees/poplar/hay/raspberries/etc...the hens hang out in there a lot and usually head out to free range a couple times a day. Well, this spring has been like an archeological dig. The hens have cleared out much of the grass and the goats (who I had for a few months) took care of a lot of the brush. I am finding bits of plastic, broken glass, metal junks, deeply buried water hoses, blocks of cement, the foundation of an old building, pieces of tarp, bungees, bricks.....some of it is so deep I can only see a tip of it and would have to do some serious digging to get the rest out. There were numerous raspberry plants growing through the tarp. None of it concerns me much except the glass. I search daily for glass and since the snow melted have found a piece every week or so. I think I got it all now. I'm quite worried about the glass but the pen is so perfect otherwise- I hate to move it. The gate is left open and the hens still choose to be in the pen most of the day. Anyway, I don't remember tossing out junk (been here for 25 or so years). I blame dh or previous owner.
We have been here for 17 years and the previous owners for 54. We have found more crazy stuff around the property than I can remember. There is metal from all kinds of implements, glass, broken crock pieces (a lot of those), wire, cows' teeth. I am sure that there will be more as the frost will lift things up out of the soil. Through blood, sweat and tears my husband has done most of the clearing of brush and old trees and rotting logs from what used to be the windbreak. We have planted many more trees and shrubs to rebuild that. It is always curious to find stuff though. Even in the house, when we have the roof done, there were things IN the roof framing that someone stuck in there that belonged to the previous family, and all we could figure was that someone must have thought they would leave a time capsule or something. I have spoken with them and they don't remember who put them there. LOL The husband was born and died in this house. I know he isn't hanging around, no chains and moans coming from the attic ;) Perhaps he is just a voyeur? I still see his wife occasionally and am in touch with the family on Facebook. We share curiosities with them when they come up.
Of course, she is joking, I only have 2 cats and they are staying here. LOL!
