My process is similar, I inserted the eggs into boiling water for 12 min. Then scoop them into a container/bowl with cold water and wait about 2 min. I dump out the now luke warm water and refill with cold water. About a minute later i take out first egg crack it and peel in the water. Repeat...
As many before me I like to express my thanks to the site owners and members. It is great to find a resource such as BYC to help us understand our latest "I want that".
We started this year with 9 day old chickens. 3 Buff Orpingtons, 3 Speckled Sussex, and 3 Austrolorps.
They all developed fine...
