We went using the Living Social Voucher. There were 12 of us all up (4 adults and 8 kids). To be honest, I don't know if I would of gone paying the full price but I guess it does take a lot of money to maintain a farm like this. The day we went it had been pouring rain the night before and that day it looked threatening but didn't rain while we were on the tour which was awesome. As previously people have said, the lady at the front was abrasive but, talking to her at the end she is quite nice - just not good with a little stress I don't think. Anyway, her husband who takes the tour was fabulous. The tour is now a walking tour but it an easy relaxed tour.
We started at the miniature horses then moved onto miniature donkey, cows, bulls, a mull (Pablo), and then more miniature horse and the newly weened horses. All of the children were given numerous opportunity to feed all of the animals and the trip was not rushed at all. Yes, the gentleman does talk a lot which is a bit much for kids (but they just kept feeding the animals and didn't care), however, what he had to say was very informative, interesting and showed such a passion for these animals.
There was also a little room with interesting relics from times gone by (including a rotary fridge) which is worth having a walk through.
As for the Chihuahuas, there had heated beds in their little run so they were quite happy.
We didn't eat there but the café area had a real relaxed feeling and overlooked a beautiful stream where the turtles were.
Nice drive out and a fun morning for our group.
