I didn’t respond earlier as I didn’t want to tempt fate !! I guess I’ve been lucky.
24 hrs. there was some improvement, alternating between scour and more solid. 48 hrs. all solid no scour. So it seems to point to a worm problem but no local FEC counts service available, must try and find one for next year.
They were due to ‘go’ this week and I hadn’t wormed them before because the field hadn’t seen livestock for 20 years, I thought it was safe enough!. I’ll know for next year..
