you change the feed, keep checking to see if it still has the
poops and if it does take it to a vet, he may have worms and he'll
probably be dehydrated.
Diarrhoea could be due to a change in feed (it can take up to 10
days for the microbes in the rumen to adapt to a new feed), worms,
bacterial infection (salmonellosis, yersiniosis), coccidiosis,
eating a toxic plant. It depends on the colour, smell and
consistency of the diarrhoea - if it is worms or a bacterial
infection it would be best to get the faeces analysed by a
veterinarian to enable the best treatment regime.
