I know the feeling. I was a bit overzealous in setting up the brooder. Spent a lot of time fiddling unnecessarily because I am so excited to get them and only have motivation to do chick-related things until they get here. BYC is chick-related, so it's an allowable activity
Poulettes and chippie - what are you getting and from where? We ordered a Barred Rock, a Partridge Rock, a Buff Orpington and 4 Silkies in white, black, and red. The silkie availability is what led to such a long wait - they were unavailable until months out.
