Hi I have two cade lambs that are about 3 and a half months old one of which isn't gaining any weight. He's out at grass with creep feed available which he's not bothered about as he's got his belly full of grass, he isn't scoured at all and has been wormed, overall he seems completely happy and healthy other than he's not gaining anything. I know he was fed with a stomach tube before I got him but he was bottle fed by me until weaning, i dont know if this would effect him at all?
Im wondering what could be done to help this? Thank you!
