Just to put some minds at ease. I have plans to cross lines and call them Ron's Birds. But the chickens I got from Pauletta are Ron's lines and I do plan to breed them with the chickens I got from Ron. Same line no issues imo.
Then if one of my HRIR hens tuns out to be a touch under breeding quality I plan to put her in with my layer group and I plan to keep my roosters who are not in breeding pens in with my layers. Now unlike Bob I don't have a set up good enough to set eggs every 4 days. The best I can do is once a week. So there will be room in my incubators for eggs from my layer group that when they hatch I will call barnyard mixes. I will keep some of the mixed chicks and I will sell some of the mixed chicks on CL to help pay for feed. Once I got the incubating process down, it did not take me long to learn that cheap barnyard mixes sell for more than my fresh eggs.
But I really don't have plans to sell HRIR chicks anytime soon. I promised a young hen to a local person but other than that one person I want to expand my HRIR flock and the way to do that is to choose from 6-8 month old chickens, not sell off chicks. Plus with setting at most 15 eggs a week, I only plan to get about 5 females from a hatch. I want to be able to choose the best and keep the others for layers.
Now there is a good possibility that I will be getting some eggs that I can't set come March or April. I still have not decided what to with those. I don't really expect to collect enough to ship with at most 3 breeding hens. I'm thinking I will be enjoying some nice omelets.
Most importantly, if I ever mixed in a HRIR from another line foolishly forgetting all of the wise advice here, then I would have earned the right to call the line mine. I would have the 5 yrs ahead of me to start the fixing of the mixed lines too. I just don't see it happening. Now I have a few fun things in mind with my mixed flock, but I can see the time it will take to mix the mixed mutts, and those projects are just for fun in the mixed layer pen. Kind of a lets see what kind of chicken I can get. But there is no way for me to duplicate it and invent my own breed as the sires I started with were eaten by an owl and the egg layers have been re-homed. But I still can have all of mixed breeding fun I want in that layer pen.
