I have 3 chicks now, but think I will have to 'relocate' one of them. I want to get 2 more on Monday (they will be just 5 days apart in age). Will this be OK? Will they flock together? Is there anything I have to take into consideration? The 2 I have now are a Rhode Island Red and a Black Australorp. I want a Barred Rock and not sure about the 4th (maybe 2 Barred Rocks?). Will they be OK right away together or should I plan to have them semi-separated in the beginning? thanks for any feedback- I'm quite new at this whole chicken experience!
