I've got about 7 eggs that are due to hatch on the 24th, and I just ordered 35 of the straight run surprise special chicks from ideal, they are hatching on the 19th and being shipped that day. So would it be ok to put in my hatchers with the older chicks from ideal. I plan on giving them a day or so transition into the new world before tossing them in. Also, if that is ok, then is there a good way to mark my chicks so I can recognize them? They are mutts and I'm going to be giving away some of the idea chicks after a week or so to some kids to show in the county fair and I don't want them to get one of my mutts on accident.
