A low hatching rate despite using a good incubator can be caused by several factors:
1. Egg Quality Issues
• Infertile Eggs – Poor fertility due to weak breeding stock, improper mating ratio, or low s***m count.
• Old or Poorly Stored Eggs – Eggs should be incubated within 7–10 days of laying and stored at 55–65°F with proper humidity before incubation.
• Dirty or Contaminated Eggs – Bacteria can pe*****te eggshells and kill the embryo.
2. Incubation Conditions
• Incorrect Temperature – Ideal temperature is around 99.5°F (37.5°C); too high or too low can lead to weak embryos or failed hatching.
• Humidity Problems – Improper humidity can cause dehydration or drowning of chicks.
• First 18 days: 50-55% humidity
• Last 3 days (hatching period): 65-75% humidity
• Poor Ventilation – Lack of oxygen or excess CO₂ buildup can suffocate embryos.
3. Egg Turning Issues
• Not Turning Enough – Eggs should be turned at least 3-5 times per day for the first 18 days to prevent the embryo from sticking to the shell.
• Uneven Turning – Some eggs may develop better than others due to inconsistent turning.
4. Bacterial or Fungal Infections
• Contaminated Incubator – Regular cleaning and disinfection are needed to prevent disease.
• Eggshell Contamination – Handling eggs with dirty hands or exposing them to damp, dirty nesting material can introduce bacteria.
5. Genetic or Nutritional Issues in Breeders
• Inbreeding Weakness – Poor genetic diversity can result in weak embryos.
• Deficient Diet – Breeder hens need a diet rich in protein, vitamins (A, D3, E), and minerals (calcium, phosphorus, selenium) for strong eggshells and embryo development.
6. Power Outages or Temperature Fluctuations
• Even short power outages or unstable temperature settings can kill embryos. A backup power source is helpful.
Happy Hatching🐣🐣🐣
