My new chicks arrived today... 3 silkies, one golden spangled hamburgs, and one golden sebright. The poor sebright was not looking too good but after drinking, eating, and resting it seems a bit better. Anyways when I opened the box, they were ridiculously smaller than my 2 weeks old standards and bantam (one RIR, one EE, one red star, one australop, one rock, one silkie and one 3 week old silkie), therefore, I decided not to add them together because the new ones are too weak yet, however they can see each other. I was thinking to keep them separate for 2 weeks and after add them. Do you think it's ok or should I wait even longer?
