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.
We ordered from My Pet Chicken a RIR, one australop, one red star, one barred plymouth rock, one easter egger bantam, one white silkie, and one golden spangled hamburgs. The wait was so long because of the silkie and the golden spangled hamburgs. Now I just hope they won't turn rooster (I paid extra for pullets but with bantams it's tough though)
