term meanings

[AwallRooster]

Can someone explain the terms '"pullets and ""St.run" in the Plymouth Rock breed.
And the term ""lockdown"as far as incubation? Please help I'm dumbfounded! !!

 

[1655ot]

Pullets are female chickens that haven't laid an egg. Straight run means chicks straight from the incubator and have not been sexed.
Straight run are approximately 50/50 male and female. Lockdown for an incubator occurs 3 days before eggs are scheduled to hatch. It means the incubator is not opened to turn eggs or add water. It's "locked down".

 

[NYREDS]

A pullet is actually a female under one year old. At a year old she becomes a hen. These terms apply even if she never lays an egg.
Straight run means chicks that are not sorted by sex, rather they are delivered as hatched.
Lockdown is purely a BYC term that was defined correctly above.

 

[farmerChef]

Pullets are female chicks (cockerals - male chicks), under 1 year of age

St. Run(Straight run), mix of cockerals and pullets

lockdown, 3 days before hatching, you stop turning eggs and raise humidity, its also good to keep the 'bator closed until all chicks are hatched to keep ones in the process of hatching from shrinkwrapping (membrane shrinks because of low humid. and chick gets suck in egg).
