After giving medicine to one of the sheep, the Emmerdale star admitted the smell was making him feel unwell. He held on to the side of a gate to catch his breath and said: “It smells strong this stuff, doesn’t it?”
However, a queasy Kelvin replied: “I’m going to have to stop, I feel like I’m gonna faint.
“Whatever that smell is, it’s gone up my nose. I feel lightheaded.”
He told Jilly he felt like he could “hardly breathe” before she scoffed: “They must have been kind to you on Emmerdale, I’ll tell you that.”
Kelvin’s Big Farming Adventure airs BBC One on Monday, 17th January at 8.30pm.
