This is "Blanch" or at least I thought...here she/he is at 5.5 weeks. She/he is a cuckoo murans that we bought from our local grange farm supply. Within a week of getting all of our new chicks, (all were 3 days old) this one was almost twice the size of all the other three with a much larger comb! Also much more aggressive and protective of the other chicks. I have been pretty sure it's a roo since then but would love more opinions before I find him a new home. Our city doesn't allow any roosters in limits. I'm also super bummed as we were greatly looking forward to the dark yummy eggs...
