Hey everyone! First post and first time chook keeper here. I have four chickens, three hens and a rooster. Two Australorps and Two Isa Brown X's. They're 8 weeks old now and I've had them since day old from a friend. I allow them to free range all day from dawn to dusk in my large backyard and they seem to be eating plenty of grass, other leafy greens and insects and I also feed them a soaked/fermented mixture of organic chicken starter/grower mixed with a poultry herbal based supplement (http://www.greenpet.com.au/products/GREENPET-BIRD-&-POULTRY-SUPPLEMENT.html). Do I need to be feeding them anything else? When, and how, do I move them onto a layer mix and would it be better for me to introduce that dry or keep it soaked/fermented as I'm doing now with their chicken starter? Thanks everyone!
