My advice would be to plan space for them carefully. They will grow FAST. The biggest mistake we made on our first hatch was not being ready for that. Although, we did 40 odd so it was a bit more major. But in 10 or so weeks time you are going to have 6 nearly full grown birds. Plus, what about any cockerels? They might all be cockerels or you might not get any. Are you going to keep them? Eat them? Do you have any existing cockerels that might try to kill them? You don't want to get in that situation where you can't keep them, can't give them away and can't face killing them. Do you want the boys getting it on with their sisters?
So it's planning really. Have a good idea of where they are going to grow and live and assume they will be full grown sooner than later. This year, we are holding off hatching until we have all the brooding, housing and pens totally in place to take them through to point of lay or slaughter. Lessons learnt!
