My Rancher Isn't Sheering Sheep! Help

[bela1225]

I tried making an automatic dye far and it was working for a while.  I have it connected to a pulverizer so the colored wool comes out the back.  Then the dye goes into a chest and the string goes into another chest.  After that the string goes to a steam dynamo to be converted into power.  For a while everything was working just perfectly.  Now for some reason it isn't working at all.  It won't sheer my sheep and I don't understand.  The sheep are fully grown and everything.  There is a redstone signal going to the rancher and is says it's full of power.  I'm not sure what to do.  Please help.

Thank you!

Try breaking and re-placing the rancher.
