Put this is your code instead of your setup code...

        clrf PORTA
        clrf PORTB
        clrf PORTC
        clrf PORTD
        clrf PORTE
        bsf STATUS,RP0
        clrf TRISA
        clrf TRISB
        clrf TRISC
        clrf TRISD
        clrf TRISE
        movlw b'00000111'
        movwf ADCON1
        bcf STATUS,RP0

All the port pins other than RB are floting inputs which can cause lots
of headaches.

The data books specify C values as pF not nF as you are using. Whether
there is a reason for this I don't know.

Try 300pF and 100K for Fosc = 28KHz. You will still need to slow your
loop down to see all the LEDs change state.


Try this for your fuse setting. Make sure it appears only on one line in
your source code.
