A small update:
One of my incubators with Half Fluffy / Half F1 eggs finished last night. Several of the chicks were able to hatch on their own, without intervention. At least 3, possibly four of these have fluffy feathers!!! Two Splash and One Blue, with a Splash maybe.
However, a small handful did not hatch as easily, they zipped before fully absorbing the yolk. Normally, I won't help chicks (especially after a 5 day lockdown!), but these are fluffies!!! The membrane around their zip-line had dried and was stuck, with the rest of the membrane still soft and moist. I have these ones isolated in a seprate brooder, as they are obviously weaker than their siblings. If any survive and are fluffy they will be marked and used in case of last resort.
Pictures this weekend!
* A second incubator with the same eggs is scheduled for lockdown on the 26th - should have plenty of fluffy chicks to work with!
