The companies own the rights for their developments. There are a lot of people who like to experiment with breeding including myself. Every year I do a breeding project. This year is support for my breed crosses of last year. This is a female from a cross of a Rose Comb Rhode Island Red male with Rose Comb Rhode Island White females. My Single Comb Rhode Island Red male with Single Comb Rhode Island White females produced excellent laying Red Sex-Links.I haven't read this thread completely through so I don't know if the point has been made before but knowledge of the breeds/crosses not withstanding, patents do expire and I'm wondering how that is dealt with? I know Big Pharma catches hell with folks who want to put out their own version of big money-makers and if State Security secrets can be gleaned through espionage, chicken pedigrees should be a walk in the park...???
Just musing.
My SC RIR male/SC RIW females cross produced excellent layers, they seldom skipped a day. I was counting the eggs they layed and when I did my calculations it averaged 6.5 eggs per day per bird. After about 2 years they were down.
I thought I may get the same with the RC RIR male/RC RIW females but got a real surprise.
I sold her and another exactly like her from the same hatch, they are excellent layers.
This was her as a chick I thought would be a male. I was intending on processing (him).
This is another chick I didn't keep. I thought it was a female. I'm repeating this breeding and will keep all of the chicks this time.
Here are the chicks shortly after they hatched with some RIR chicks.
