The chap text me last night saying he will pay us £75 a calve but he said this last time and soon as all calves where in unit he cut it to £65. My father in law rang me yesterday and said he wants us to rear his calves and he will pay us 80pence a day per calve
Sounds like you're rearing your FiL calves then.
That the calf owner is only texting you rather than ringing - or better yet seeing you face to face - speaks volumes.
