I have 2 hens (rhode island red and australap) which just laid their first eggs yesterday. I have 6-8 wk babies, two that are very large and are outgrowing the brooder area, one blue wyndotte and one barred rock. The silkies are still small and for some reason I have a runt for a blue-red wyndotte as she is the tinest out of the 5. Anyway, my older hens range my yard during the day. Do you think it would be ok to let the bigger two range with the older ones and then have them start roosting with the big girls and later introduce the other small 3. Or would it be better to wait and have the new 5 meet the other 2 all in one day?
