Is Chicken breeding anything like Plants?

[Papaw-John]

I know this may sound silly, but I am seriously wondering. Is Chicken breeding and crossing anything like crossing Plants? The reason I ask is because I am interested in crossing plants. You can cross two different types of tomato for example and produce a hybrid that produces a larger faster developing tomato for example. If you take the seeds from the larger tomato and plant them only some of the plants will produce the faster growing larger tomatoes. But, if you take the seeds from one of the plants that has the desired traits and plant them you get the same thing. Some of the plant will exhibit the desired traits some won't. If you take seeds from the plant with desired traits for 7 generation, you will developed a new type of tomato plant that will produce the same plant generation after generation. You can buy a type of hybrid garden seed, plant them and save seeds from them. By selecting seeds from the fruit that is desirable over 7 generations, you will have taken a hybrid and produced a stable plant.
Is there a number of generations to produce a stable breed of chicken in the same manner?

You are a little misinformed in your genetics theory. Whether it is plants or animals, if the desired outcome is not homozygous in its gene pairs, it will never breed true. As long as one gene pair remains heterozygous, no number of generations will cause it to breed completely true.

Ya idk about plants but what you describe doesn't work for chickens.
There is no magic number of generations that makes it breed true.
It breeds true when you get the right genes in place. You have to bring in the genes you need and breed out the ones you don't want.
That may take a couple generations or an indefinite number of generations.
All depends on many things. What you start with, where you are trying to get to, how many you hatch in a generation, how lucky you are with which genes are inherited in any one chick, etc.
I don't agree that everything needs to be homozygous and not a single set of genes can be heterozygous for it to breed true.
You only have to worry about what shows or what would alter what shows. Other genes can be heterozygous and never matter.
Just an example that I have is white leghorns. You can have a lot going on under their white that doesn't matter if its homozygous or not.
They can be blue, black or splash underneath and it doesn't matter and blue never breeds true. They can be heterozygous for things like mottling and it won't show so doesn't matter.
You can also have sex linked genes like barring that may or may not breed true depending on whether cockerels have two copies or not but it won't matter because it won't show.
Probably didn't explain this in the best way but maybe you get the idea.

It is not really my knowledge. I read it in the book

"Breed Your Own Vegetable Varieties: The Gardener's and Farmer's Guide to Plant Breeding and Seed Saving, 2nd Edition"
