Yes, they do look like pullets. You do not need to separate the rooster. Unless a fertilized egg is incubated, there will be no chicks. An egg must be kept at a constant 100* for at least 48 hours to start development. If you leave the eggs out on the counter, they will not spontaneously start developing. When you want eggs to hatch, collect the eggs that you want. To make sure you collect the correct eggs, you can mark their vents with gel food coloring after they go to roost. In the morning, the eggs that have streaks of color are the ones you want to hatch. Males will have silver/white based down. The female chicks will have a golden based down. They won't look like typical red sexlinks, but the basic rules still apply. Red/gold colored birds will be female. Silver/white colored birds will be male.
This is brilliant! Hadn't heard of this before! We're not currently hatching any chicks, but this will come in handy in the future.
