Ok, so I sorted through my brown coturnix's this morning and out of 27 birds I only have 7 hens!! Im sexing them by their markings, the hens having the speckled breast and the roos having the rust colored breast. Which seems to be pretty right on as the only ones I have ever seen crow are rust colored without spots on their breast. So that means I had 19 roos in with those 7 poor lil hens! Maybe that is why I haven't had any lay yet?? They are around 8 weeks old now, the roos have been crowing for a little over a week. But not one single egg yet ..maybe soon??!! Im feeding the an 18% protein turkey/game bird feed and they eat it up like their starving LOL I feed them twice a day as they finish it off within the day. So how many roos does everyone suggest I keep with these 7 girls? I kept back 4 of the nicest roos from the group to put with them.
