If you don’t want to use "keys", here is a fancy way to do it. 
my %hash = (
    a => 1,
    b => 2,
    c => 3,
    d => 4,
    e => 5,
    f => 6,
    g => 7,
    h => 8,
    i => 9,
    j => 10,    
);

my $hash_length = %hash;
# To get actual length you would need 'scalar keys %hash'
# But we are not using 'keys' here so lets get the length other way 
$hash_length =~ s{/.*}{};
foreach (1...10) {
    my $rand_num = rand $hash_length;
    # Make sure number is even.
    $rand_num = ($rand_num %2) ? ($rand_num - 1) : ($rand_num);
    my $key = (%hash)[$rand_num];
    print "$_\t: $key\n";
}

# output
# 1       : e
# 2       : d
# 3       : c
# 4       : j
# 5       : a
# 6       : e
# 7       : e
# 8       : c
# 9       : j
# 10      : e
