| Question | Answer |
| In judging laying hens, what are the five factors that determine short term production? | 1) Comb development
2) Facial Pigmentation
3) Spread in abdomen skeletal structure
4) Vent color and shape
5) Wings |
| In judging laying hens, what determines long term egg production? | Color of the shanks |
| If the facial pigmentation of a hen is yellow, are they in or out of production? | OUT |
| The whiter the shanks, the MORE or LESS eggs the hen has laid. | MORE |
| Oval vent shape = IN or OUT | IN |
| round Vent shape = IN our OUT | OUT |
| Dry vent = IN or OUT | OUT |
| Damp vent = IN or OUT | IN |
| If the vent is yellow, is the hen laying or not? | NOT laying |
| True/false: There is a relationship between grade and size | FALSE. There is NO relationship |
