Sorry for not seeing this earlier.
They are in rude health and barrelling around the place and making it their own. Stock fencing isn't intended to restrain small pigs, and it certainly doesn't. One made it upstairs in the chicken coop, much to the surprise of everyone. To paraphrase Basil Fawlty, I can look out of the window most days and see herds of piglets sweeping majestically across the field. Generally in pursuit of sheep.
They'll definitely be ready to collect anytime from 18 July, just text me and let me know when is best for you to collect.
