Currently I am using one photon to send encoder values to a second photon for data processing because I have ran out of available digital and analog pins. I would like to have everything on a single photon. Is there an available breakout or device that can help me expand the number of pins on my photon?
You have lots of options. Hunt around for mux or multiplexer boards or expander boards.
One example of many many options…

@lightbry, there is also the MCP2317 (I2C) and MCP23S17 (SPI) with 16 digital I/Os and an available library in the web IDE.
