Safe age range?

[fshinggrl]

I ordered some chicks that will be in April 12th, but that place didn't have the breed I really wanted so I am needing to order some others as well. What is the 'safe' age range that I can put together? Say, if I could get a shipment about the 10th? Or can you go a little further away?

The last brooderful of chicks I raised I added a couple new chicks twice during the first week and nobody even batted an eyeball. I did watch them to be sure but there was no trouble at all. If yours are arriving within days of each other they should be fine.
