Geoff-
Thank you for the response. Will start to think of 22 hour method as a guideline- not exact science. While hunting my imprint last year- I would feed her up on her first 10 jackrabbit kills. After that I would go for the occasional double and feed her only the heart and lungs on her first kill. She ended the season with 25 heads- which I was pleased as she was slow to gain success in the fall.
I took note of your reference to “mid winter anemia” – which makes a lot of sense. “Their system will gradually get depleted of micronutrients and other resources, in a condition Pat Redig called "mid winter anemia".”
