Yes! You are progeny testing. You are on the path to breeding up your flock.Right now I have those Orpingtons in the bator Progeny testing. I am not going to show them if they are bad producers.
It is a test. I think to some extent free ranging is progeny testing. We use culling of the unsuccessful. I never collect eggs for incubation in some of my layers they have small breasts or pinched tails. I eat the ones I don't like or do not breed better.
I think the chicks I have growing up now with the RIR are some of the best chicks I have bred. These were a test. The hen is young, just a year and I was not sure if I wanted to use her half brother since I knew nothing about his father. Normally I do not like to propagate with unknown. These chicks are really nice looking.
There are many many things to progeny test for. Fertility, vitality, egg production, breed type, feather quality, and so on and so on.
Good record keeping and marking chicks and then following their life span. That...My friends is good progeny testing. You start on day one and shoot for a ten year date to see where you get. That is what I'm talking about.
