I bought 4 Ameracaunas and 4 white leghorns this last week. The 4 Buff Orpingtons I ordered won't hatch until next week.So by the time they get here my other 8 will be 2 weeks old. Is this too much of an age difference to keep them together? Should I keep the BO's in a seperate brooder? I hate to keep them seperated and then throw them all in the coop together when they're ready. I fear that will be disasterous. Any advice?
