This is Mushroom (my 4-year-old says this is a great gender-neutral name, fyi). I posted pictures of him as a baby, but no one could really tell the breed, though everyone guessed boy. About 7 weeks old now and we're really curious!
They're still babies, but I'm really interested to know what more experienced folks think. My husband got them from Tractor Supply; 5 red sex links and these 5 mystery chicks. Did my best to get clear pictures, but I can take more.
