Speaking of getting rid of chickens...
I have 5 red pullets. I need to get down to two. How do I pick my two? Who is the most friendly? Who is the biggest? Looks aren't an issue bceause they all look the same. Who seems to get along with other chickens? How do I pick?
Widest leg spread, widest base of tail (looking from behind, the upside down V made by the tail), fuller/rounder deepest chest (keel). Means there is more room for organs and egg laying. After that, I'd go with who makes a harmonious flock.
