Chicken purchasing question

Tomorrow Hubby and I will be going to a farm auction, a typical spring activity here and opportunity for him to load up more "man treasure". (Whatever keeps him occupied, ya know what I mean?) But I was reading the sale bill and it says,
"15 nanny goats, 2 hogs already bred, 3 ewes, 8 turkeys, 12 rabbits, 17 pheasants, 1000 chicken pullets, small group of Bantams, 1 pair quail. Bring own cages to haul"

If I were thinking of bidding on those Bantams, what should I check out on them first, prior to bidding? Legs for scaly leg or something along those lines?

I assume the 1000 pullets are Cornish Rocks or Cornish Xs, and I've got 15 of those meatie-monsters in the brooder now eating me out of house/home.
