So after 7 months of raising chicks, I returned 2 roosters to the farm I got them from. They really have no clue about chickens at all. I have one pullet left in the coop by herself. She seems lonely and I wanted more than one anyway. After searching, found a farm that does nothing but poultry and drove an hour today to pick up some companions for our "Becky". They only had 1 week old chicks and they assured me that they are 95% sure they are pullets. Got 1 Barred Rock, 1 Buff Orp, 1 RI Red and 1 New Hamp Red. How can I (at what age) start to integrate them together? Not all birds are in this picture
