I am planning on adding 6 chicks to my flock this year. Buff Orpingtons, SLW, and Speckeled Sussex. My issue is that the stores are getting these breeds in at different times. Has anyone had experience on obtaining chicks in staggered time frames. Looks like I may need to wait a couple weeks after I get my first breed for the next one to be available. The SS hasn't appeared yet on their list of expected breeds. Will it be OK to put them together if I get them a couple of weeks apart if they come from the same hatchery? Will there be any integration issues with the differing ages since they are still young chicks?
