Im not sure what your looking at are spurs.
First picture with him standing facing away his spur would not face that direction.
The bottom picture the only spur i see for sure is the one on the front leg of the near bird. On the back bird that top thing sticking out of the two may be his spur and it would be a good one. jmo. They all might be spurs. They both have good beards and will be nice and fat come hunting time.
They always look bigger in pictures just like a deers rack. I am guessing just shy of 1.25"(of course that depends on what kind of tape measure you use and at what angle you hold the tape and the camera )!
