Part 5 - Troubleshooting
The Greatlander Incubation Guide
Understanding the cause before correcting the symptom.
Every Hatch Tells a Story
Even the best incubators and the most experienced breeders occasionally encounter problems. Fortunately, the developing embryo leaves behind a remarkable series of clues that allow us to work backwards and understand what happened.
Successful troubleshooting begins with careful observation. Where did development stop? What position was the embryo in? Was the air-cell the correct size? Was there an internal pip? An external pip? Were the membranes wet, dry or sticky?
By interpreting these clues logically, many hatch failures can be traced back to their original cause. Often the problem did not occur where it finally became obvious. A late dead-in-shell, for example, may have resulted from conditions experienced many days earlier.
This section explains how to diagnose incubation problems systematically and, more importantly, how to prevent them from happening again.
Topics in this section
Early Embryo Death
Why do some fertile eggs stop developing during the first week? Learn how nutrition, storage, hygiene, temperature and embryo health influence the earliest stages of development.
➡ Read: Early Embryo Death
Late Dead-in-Shell
One of the most frustrating hatch failures. Learn how to examine an unhatched egg methodically and use the evidence left by the embryo to understand what happened and when.
➡ Read: Late Dead-in-Shell
Malpositions
Most malpositions have an underlying cause rather than occurring by chance. Learn how embryo positioning develops during incubation, the common malpositions, and practical methods of reducing their occurrence.
➡ Read: Malpositions
Poor Hatch Rates
When hatchability is consistently disappointing, the answer is rarely a single setting. This chapter brings together the most common causes of poor hatchability and provides a logical sequence for investigating them.
➡ Read: Poor Hatch Rates
Sticky Chicks and Membrane Problems
Sticky chicks, dry membranes and adhesion problems are often misunderstood. Learn the difference between normal hatch processes and genuine membrane-related difficulties.
➡ Read: Sticky Chicks and Membrane Problems
Air-Cell Problems
The air-cell provides valuable clues throughout incubation. Learn how to recognise air-cells that are too large, too small, detached or displaced, and what each condition may indicate.
➡ Read: Air-Cell Problems
Temperature and Humidity Problems
Sometimes the incubator is simply reflecting conditions rather than causing them. Learn how incorrect temperature or humidity influences embryo development, and how to diagnose the difference.
➡ Read: Temperature and Humidity Problems
Recommended reading for first-time incubators
If you are investigating a hatch problem for the first time, we recommend beginning with these chapters:
- Air-Cell Problems
- Early Embryo Death
- Late Dead-in-Shell
- Malpositions
- Sticky Chicks and Membrane Problems
- Poor Hatch Rates
- Temperature and Humidity Problems
By the end of this section you will be able to examine hatch failures systematically, understand the clues left by the embryo, and identify the most likely causes with confidence.

Not every species follows exactly the same incubation pattern. Ducks, geese, ratites, reptiles and other egg-laying animals each present their own unique challenges. The next section explores these special cases while applying the same engineering principles that govern all incubation.
