It is 3.5 weeks old. But it just doesn't grow like the others. It's funny, it doesn't get pecked, but it is much smaller than it's siblings. Should I do anything special for it?
I know on most wheaton varieties, the roo feathering comes in much darker than the hen's feathers. I don't know if that is true of Marans but if it is, then I would suspect your little one is a roo.
