He should be fine - and it's not necessarily the whole toe, just that digit that has turned black. I was trying to see if we have an article on it, but can't find anything super quick - chickens have this ability to 'self-amputate' their toes, one joint at a time, as their injuries require, and go on living nice, full lives. He may hurt for a little bit, though, and maybe limp, until the process is complete.Will he be okay with just 3 tows??
