Old Yard Brushes and Hay Fork (Leeds LS7)

I have recently taken the volunteering role of caring for 9 pygamy goats. I’m looking for the brush end of old outdoor brushes or anything that I can fix to their barn to enable them to scratch their backs and encourage self grooming. They have be wooden as goats love to chew plastic. Also I’m after a hay fork to to help make their bedding more comfortable please. Thank you so much for reading 🙋‍♀️
