I'm a great fan of Shaun the Sheep.  I've been looking for these missing episodes for years, and finally found them on a streaming video site.  No one seems to have uploaded them anywhere, so here they are, for the 1st time as a torrent:

Shaun the Sheep - Season 4 - the LOST episodes....:o)
  Episodes 21 thru 30, December 8 ~ 19, 2014
  720P Streaming Quality

They seem to have fallen through the cracks, as everyone uploaded the complete series at the time in mid-2014, just before these 10 episodes were aired.  They are just a tiny-tad jerky, so if anyone has better copies I'd love to hear about it!  See these Wikipedia links, and Season 4 epsiode list in 2nd link:

Watching these always brings a smiles and chuckles to my face after a hard day, hope you learn to love these as much as I do!

Enjoy, and remember Seeding is Caring!....:o) - Cheers!
