Upon further digging I found out they did a couple more of them too. One of them isn't available online except for one brief 8 minute teaser piece: Tales from the Green Valley, where they live for a year on a Welsh farm in the 1600's. I hope this one is someday available in full!

Victorian Pharmacy was a shorter special they did focusing on medical and home remedies of the era in a recreated apothecary. This one is viewable in full on Youtube at the link.

Oh, and one more thing I discovered: I was trying to finish watching Edwardian Farm last night on the original link I provided above, and on part 4 of episode 11 the streaming cut out entirely. I was able to finish watching it on youtube, so if this happens to anyone else on that link just find it on youtube.
