we have two banties right now that are about 1 yr old. We are going to get some standards soon(about 25) and want to know at what point can we introduce the banties to the other baby chicks. Is it necessary to house them separatly as they grow?? Also when we first got the banties they were sick for about 2 weeks, not sure what they had but we fed them Terramycin and they got better. Can they be carriers to the standards at this point in time?? Or can we gradually put them together? Thanks!!
