Re: two DHCP servers in same subnet.

DHCP IP address assigning is done on "a first come, first serve basis", then
you could screw up you network. If you wan to have a "fall-back" DHCP
server, then you should look at fault-tolerance/load balancing set ups.
That is to say: another DHCP server would take over if the first one fails.

Yves:

The trick is to split the subnet's addresses into two non-overlapping DHCP
scopes, so, that use of either DHCP server will result in a DHCP client
receiving an exclusive IP address in the one/same subnet.

i.e., For a subnet mask of 255.255.255.0:
Scope 01: 192.168.1-128
Scope 02: 192.168.129-254

Each DHCP server would have the same DHCP options.
