I have a website running across multiple subdomains and each one has a favicon.ico icon file in the root of each subdomain. Each icon for each subdomain is exactly the same. Is there an easy way I can declare every icon but one with rel canonical? Or is it worth redirecting users to the original icon even though each icon is about 900 bytes?

    Why are you worried about duplication? These icons are unlikely to appear in any search results, not even image search. I can't imagine they would cause any SEO problems no matter how you deal with them. Jan 6, 2016 at 22:06

I wouldn't be concerned about duplicate favicons - it is common across many sites to have duplicates.I would not action canonicals or redirects as it is not likely to have any SEO impact.
