Is it safe to let chickens eat cooked unfertilized eggs that have been partially incubated?

[NevadaEmma]

Hello, I candled about four dozen eggs last night that have been in the incubator for about a week. Quite a few appeared not to be fertilized. (I newly laying hens and an old rooster that my not be as effective as he once was.)

There were about two dozen that did not appear to be fertilized.

Instead of wasting that many eggs, is it save to feed these eggs to the chickens once they have been hard boiled?

Thanks,

I've fed week old incubated eggs out to my flock on several occasions.. sometimes boiled or scrambled.. and never had any issues.

Never 2 dozen at a time (possibly depending on flock size).. eggs are 34% protein and 64% fat.. by energy/calorie count (not volume)..
