Please don't put perfume on your chicks! They have delicate respiratory systems and that could be fatal. Take it from someone who has asthma! I would definitely get 2 new ones. chickens are terribly cliquey... worse than 6th grade girls. The new baby should have a friend with it so it won't be the one left out of the fun and games. You know what they say about "3's a crowd!" Your other 2 have already formed a bond. Good luck.
