I've got some chicks that will be 4 weeks old this weekend. I've always heard you should wait until they're 5 weeks old and all feathered up before you put them out. I have 20 in several 50 gallon plastic totes in the spare bedroom. I'm almost finished with my new coop/run, just have to make the door. My son and gf are complaining about the smell. LOL. You can clean it everyday, new pine shavings, newspaper and they still smell. Here in N.C. it's been in the 90's during the day and upper 60's to lower 70's at night. I think they'll be fine. What do you guys think? First time using an incubator. Got 20 out 35. Ameraucanas, Polish, BCM and some RIR/Brahma mixed. Thanks for any advice.
