The dhcpd man page suggests that the "-d" flag will cause
dhcpd to run in the foreground and log to standard error.
In fact, it seems to have no affect whatsoever.

There is also a "-f" flag to run dhcpd in the foreground, without
redirecting logging. It also seems to have no effect.

The version of dhcpd is 3.0.5

Here is a cut-and-paste from my terminal:

ldap# kill -1 17115
ldap# dhcpd -d
