Hello, I'm new to chickens and have been 'lurking' around this site for a while. We have 3 six week old chicks. They're still on the starter feed at the moment plus we've just started to keep them outside which they seem to be thoroughly enjoying so they are also scratching about in the soil and eating greenery and 'bugs'. As a treat I give them yoghurt with their feed mixed in which I read about on one of the postings here. I've read and heard two opinions.....one that chickens need grit to aid digestion, the other that they only need grit when they start to lay so I'm a little confused and worried.....should I be giving them grit yet? I'd appreciate any opinions that you more experienced folk have.
