Well maybe you didn't exist either, but lockdown is not more than ten years old...probably more like 6 years old and just because it is used on two places on the internet does not make it the correct usage of a word.... nor an indication of a language trend.
It is a good description....just sounds more important than it really is. Again .....I believe diet is far more important than a half click on the thermostat or humidity controls.
Chicks that are hatched and brooded under a hen always seem a cut above the incubated chicks. In both disease resistance and breed type. I have no idea why type would be affected, but I have seen it enough times to believe it is so.
I'm still waiting for you to post the pic of you with static hair.

I do not even believe in the meaning of the term "LOCK DOWN". I incubate with no water, and frequently open the bator to remove the eggs shells from early hatches. It does not matter. They hatch out just fine. I stuff my foamy incubators with up to 85 eggs and use a beer can to prop up one end of the bator one day then level it off and prop up the other end the next day.
"LOCK DOWN" to me is more of a term used on campuses to protect our youts from being blown away by gun toting idiots who go to schools who mean to harm our kids.
