I like the organic non-GMO things, everything my 'babies' eat that is unnatural; I feel like "Wow, if I can't eat it without something bad to happen, why do they?"
My oldest chickens are 6 yrs old, the rooster was never fertile and he has circulation issues. Yes, he's up in age; but he survived a stroke, luckily he's okay! But I think that flock of chickens are strong.
BTW:
@Mrs. K ? What 'did' happen to your flock, and why don't you think the others will 'not' make it that far in age? Same thought as
@wyldflwr .
