Great kata. Big thanks and also for identifying what was wrong with my test results to help identify what was wrong with my code.

ok thanks

Please, post this in that kata's Discourse, not here.

i am very new to Codewars. Hope this question is appropriate for the forum.
I ran the Attempt test cases for The Hunger Games – Foxes and Chickens using Java.

For Random Test 1 Here is my result before/after (farm/farm2)
followed by the Before/After from test case.
//farm = C....C.C[..CCC..C.....C..CCCC.CC.CC....C.CCF..F.CCC..CCC.C.F...CC.C.....F..C.CCF..C....C..C..CCC.]
//farm2= ........[..................................F..F............F............F......F.................]
//Before:C....C.C[..CCC..C.....C..CCCC.CC.CC....C.CCF..F.CCC..CCC.C.F...CC.C.....F..C.CCF..C....C..C..CCC.]
//After: C....C.C[..................................F..F............F............F......F.................]
the After includes the "C"'s outside the brackets which to my understanding should be "."'s correct?

For onlyChickens test case here is my before/after log followed by the test case results.
farm =.C..[C.]..C....[C]..[C..]
farm2=....[C.].......[C]..[C..]
expected:<.[C..[C.]..C]....[C]..[C..]>
but was:<.[...[C.]...]....[C]..[C..]>
my result seems ok and the test case result has unmatched [ ]'s

appreciate the help to clarify. Thanks
