Chicken's blood as fertilizer?

We occasionally eat one of our roosters and I don't like to be wasteful so I would like to find a good use for the blood. I've tried some dishes prepared with it in the past and I cannot stomach them. All I can taste is iron. Blehck.
So has anyone used fresh chicken's blood as a fertilizer? I've heard of dried blood being used but what about fresh? It's supposed to be high in nitrogen but it can burn plants. So could I just dilute it? How dilute would it need to be? I've also read that it can be added to compost and it will help speed up the process. Will it attract predators or other pests?


Not sure if this is the right place for this so moderators feel free to move this anywhere you feel appropriate.

When I process chickens, I always add the blood and inedible guts/etc. to my compost (as well as the bones after making broth). I don't have problems with this attracting rodents, BUT I always make sure to bury it deep in the middle of a nice, large, hot pile. I imagine that it would attract pests if I didn't bury it deep enough in the pile!

I've been watering the plants in my greenhouse with my kitchen greywater and sometimes urine for several years, and it works great. I haven't done any butchering so it was never blood per se, but my experience leads me to believe that you could just dilute it and put it on the soil or in the mulch below your plants, and the plants will love it. For urine, I've seen dilution recommendations of 1 in 4 to 1 in 10. Blood might have a similar intensity of salt, so dilute it at least 1 in 4. If it soaks into the soil, I don't think it will be attractive to predators, but I've never raised chickens so I don't know for sure. And I can tell you, the skankiest smelling greywater loses its smell within 5 minutes of being poured onto soil in my enclosed greenhouse, so I expect rooster blood would get neutralised pretty quickly too.
