when is this acceptable. Both are mixed flocks. The older batch hatched tuesday and they are a white leghorn. partridge cochin. Buff orpington, golden campine, speckled sussex, Silver laced wyandotte, golden laced wyandotte, and an easter egger. My new batch of 4 is planned to ship the 26th (about 2 weeks) and is a buff laced polish, white crested blue polish, blue laced red wyandotte, and a welsummer. When will these chicks be able to merge together, and should i be worried about the polish's getting picked on. Those are going to be more of my pets since they aren't very good layers and i want to make sure that they will be ok. Thanks for your help!
