I have an orphan lamb who lost its mum at about 1-2wks old. 2 weeks later and she’s still refusing the bottle. We have to tube feed her to get anything down which has become a pain to say the least. We’ve tried letting her for longer so that she gets hungry, little and often, different teats. Nothing working so far. Any ideas to get her to accept the bottle? If not, at what age can I forget the milk and just leave her with creep?
