I am intresting to get some idea of how to age fox cubs to get some idea of the breeding times this year. Is there any books with good details.
Currently this month ( LATE MAY) I have seen cubs almost identical in size to a vixen (I shot the vixen) and the cubs were alongside.
We had one in a larsen trap the size of a small cat and I have shot one about the size of a adult rabbit.
Any ideas to the likely ages of the above.
