Hi. We've 14 quail at least 8 weeks old who haven't laid yet but now appear to be moulting....would this stop their first lay? Not having much luck sexing them either...two are white Texas a &m, two cinnamon coloured, two big, dark and speckled and the rest Japanese. Fed on marriages quail pellets with mealworms added in. They have a grit bath but no other additional calcium etc. Light for about 12 hours a day, Kent in uk. Any advice would be great...especially about sexing!
