During artificial incubation, excessive humidity commonly causes which effect on developing chicken embryos?
Correct answer: A. Insufficient loss of egg weight and a small air cell
- A. Insufficient loss of egg weight and a small air cell
- B. Excessive loss of egg weight
- C. Premature closure of the shell pores
- D. Complete prevention of yolk formation
Explanation
High humidity reduces water loss from the egg, leaving the egg heavier and the air cell smaller than expected at hatching. Proper humidity is therefore monitored partly through egg weight loss and air-cell development.
