Today’s musings (‘\u03c9’<\/em>)<\/p>\n\n\n\n

It’s become such a pleasant season, hasn’t it? Country living at this time of year is absolutely wonderful!
A freshly brewed cup of coffee enjoyed outdoors while feeling the autumn breeze\u2014such a luxuriously indulgent moment (‘;’)<\/p>\n\n\n\n

Well, I’ve had a wonderful opportunity these past few days and have suddenly decided to raise a few hens.
At first I thought naively, “Great, I won’t have to buy eggs every morning\u2026!” (laugh).
But when I calculated the cost of the cages, water and feed containers, and feed itself,
I faced the obvious reality that “there’s actually quite a bit of initial expense and effort involved!” <\/p>\n\n\n\n

Well, this is a luxury hobby that you can only attempt if you have such spacious grounds and some flexibility with your time.
I’m going to live by the philosophy “do everything you want to do in life.”

In any case, I’m really looking forward to eating fresh eggs from hens I’ve raised myself (\u00b4\u03c9\uff40<\/em>)
So I’m making preparations with excitement every day! <\/p>\n\n\n\n
