I have four three week old serama chicks. The other day I noticed one had red wattels begining, and I thought Roo? Then tonight I heard all this ruccas in the brooder and two of them were fighting and chest bumping like two teen age boys! The one with the red starting on the lower sides of it's mouth and the littelest one. and sure enough that little one is getting the red around it's mouth too! Is it too early to suspect Roosterhood?
