a foul egg

[tophatsRcool]

im been incubating chicken eggs. have not hatched in 21 days. checked half were fully developed but the other half were under developed & all dead.

Next time keep a close eye on your temps, some chicks can take a couple days longer to hatch if they were kept at a lower temp. This may explain why they looked fully devolped but didn't pip yet.
