some stray chickens wandered into the yard and one of them is a New Hamp Red and i read that Productions are made with them and RIR so i thought if i bred him with my RIR hens then would their offspring be Prod Reds?
As I've understood it, yes, that would be the general way most hatcheries have made their production reds by crossing the RIR and the NHs. Some say that all hatchery RIRs are production reds, but that is not the case--for example, in the past, Ideal has always sold both RIR and production reds as two different birds, though, of course, their RIRs are not the nice, dark breeder types.
I've been at the local feed store, who buys about 5000 chicks each year from Ideal, when their production reds and RIRs came in--two separate breeds/types.
If you cross a NH and a RIR, you can call it whatever you like-it will be a good layer for you.
First there is no "red'' at the end of New Hampshire. The breed is a New Hampshire.
As for a Production Red,
There are two true types of "Production Red" one is selectively bred solely from the R.I. Red just like the New Hampshire but solely for egg production.
The other type of "Production Red" and what most hatcheries offer is a cross and the result of a R.I. Red with Leghorn blood added.
Some Hatcheries clam that there R.I. Red /New Hampshire cross is a Production Red but this is just a cross and not a true Production Red.
A production red is a simplified name to describe Rhode based red birds that have been selected to be productive layers of large brown eggs. There is no simple answer. Unless someone has the inside scoop to all of the breeding decisions of any given hatchery, they cannot answer.
In the past laying strains of New Hampshires were used to improve some laying strains of the Rhode Island Red. Improved meaning to improve quicker feathering, and faster maturity. A month's head start on laying being the improvement.
Could you call your crossed red birds production reds? If you thought the results were equal of what many would expect from a production red. Equal being quantity of large brown eggs of good shape and quality.
