Thanks everyone for all the greetings.
Chicks are doing well, growing fast. You know you have some small breeds when the chicks that are a week younger (about 6 days old) start out-sizing some of the older chicks (about 13 days old). The largest so far are the Barred Hollands and the Guinea Keets, and the smallest are the Cubalayas. The younger ones fall into the middle of the range, although the broilers are not far behind the Hollands size wise. Still have them separated for now, might consider putting them all in the same brooder next weekend. Will depend on feathering of the younger ones, although a lot of the Cubalayas seem to be slow to feather.
Time to focus on the coops now. Plan on keeping them housed where they are currently at by partitioning it off and adding roosts, until coops are finished. Yes I did say coops, plan on keeping the breeds separate, but that plan may change.
