We have 9 chicks- 8 weeks-10 weeks old (including 1 rooster, Steve). Today we brought home two 4 week old chicks. We have them together, yet separate but having them in a smaller pen in the run and we screened off a section of the coop just for them too. How long should I do this segregation for? Now for the chicken drama. They are all going nuts. Steve is ******. Flyer (who is normally mellow) is after all the other girls, chasing them and jumping on them and grabbing on to them. What is going on? Let them be? Thanks guys!
