I have to be at work at 6 am, I get up at 4:30. Summer is fine, birds are up, bunnies are scurrying, the sky is bright. Winter? It's cold, there's ice on the road. Was that a shadow by my car or a bear?
"I travel in from (community 15 miles away) and I can't be bothered to make that long trip to be at early appointment or pick up my products "

Glad you got your own chickens, that's nice...
