After a few phone calls over the last few days I've finally found a Lambing placement! :D
The farm is in Hints - about 15 minutes away from here, and I've just been up to the farm to introduce myself.
They have around 600 sheep, which are all going to be brought inside the sheds in a few weeks, so we will be Lambing indoors.
I'm really excited and I'm starting on the 15th March at 6 o'clock in the morning! but it will be worth it.
