I am so happy and relieved for you that your chickens are ok... I have had two fox raids over the last three weeks, one at just before 5 pm and the other at about lunchtime. I now have no chickens or roosters left at all for the first time in 5 years but I do have lots of little graves.

I was home both times.
I don't mean to be a negative nancy (apologies to anybody out there named Nancy) but my point is that there is never any guarantee. I always thought I was safe as long as my chooks were away before dark and let out after dawn. I have learnt the hard way that this is not the case. I also lost 5 last December at 2 in the afternoon to a fox pup (I was eyeball to eyeball with him) but I thought this was just a one off and unlikely to happen again. So, nearly 5 years with no problems then 3 hits all in the last 7 months.
I won't be getting any more poultry now until I can enclose them completely.
Having said all that and bringing everybody down (sorry), you can't be there all the time, you can do everything right and it may never, ever happen to you and your chooks. But with free ranging chooks, it is best to be prepared, cause when you least expect it, it just might.
