well, my new 3 chicks are only 5 weeks old but my neighbor and I (um, she love chicks, too) today bought 2 more chicks each.!!!! Ah, I had not thought of more but couldn't resist. I bought another Buff Orpington and a New Hampshire Red. They are so TINY. I forgot how tiny they are. Feel more confident this time around. New chicks are in a brooder inside the coop where the bigger ones are. How old do my brand new chicks need to be before I blend them with the bigger ones? Happy chick mom!
