I have a group of Jubilee Orpingtons that I bought at 1 week old from Craigslist. Finally they stared laying and I incubated the eggs. Now these are my only chickens I have now so there is 0 chance of them being mixed on my end. Here comes the trouble part: When the eggs hatched the chicks are not the same color at a day old! Some are dark chipmunk colored while some are yellow with dark stripes... I have raised mottled Cochins, Favorelles, Brahmas and they have all hatched a uniform color. This has blown my mind and makes me afraid that maybe the flock is mixed with another breed and not 100% Jubilee Orpington. I really like them and would hate to start over with a new flock but I am not really wanting to breed mix breed chicks, either! Just looking for opinions on what everyone thinks! Thanks!
