Hi all! We are so enjoying our life with chicks. It is busier than we thought, but so enjoyable! A question for all you veteran chick raisers out there... we have 6 chicks (3 black australorps and 3 white silkies who are a day away from 5 weeks old; we also have 6 chicks (3 buff orpingtons and 3 silver laced wyandotte who are a day from being 10 weeks plus the remainder of our flock (2 speckled sussex, 2 wellsummers, 4 easter eggers and 3 salmon faverolles) who are a day away from being 9 weeks old... at what age/size should we start integrating the 5 weekers and the older groups together? Presently they all share the same coup but we have a built in brooder where the younger 6 sleep and spend a few hours a day. The bulk of the daytime hours are spent on the floor in another brooder type box with hardware cloth sides so they can be eye to eye with the older ones. The older girls spend their time roaming between the coup and fully enclosed run. Any suggestions would be greatly appreciated!
