latest guinea hatch

I packed the incubator full of eggs (42 total) 6 weeks ago. Two of those were not viable (candled at 10 days). Of the 40 remaining, 29 hatched. Most are lavender, but some are purple-lavender crosses. It should be interesting to see their adult colors.

strange eggs

Sometimes eggs are not "normal". There are many ways to define what constitutes abnormal, such as the following called a "softshell egg". (Even an egg that is not within a prescribed range of size can be considered "abnormal" even though it is perfect in every other respect. Mass production requires consistency for packaging purposes.) It's an egg not just with a soft shell, but without any shell at all. The contents are held in place by the membrane found just inside the shell.

The egg shown here is like a lump of jello -- easy to pierce, but held together easily by the membrane. Notice the interesting twist on the end holding it together.

Softshell eggs can occur for a variety of reasons, most often by lack of calcium in the diet. Young birds tend to have a higher incidence of abnormal eggs until they are more mature.
