I have Black:Lavender Orpingtons and they can be little stinkers as flock bodyguards and they always want to get their share of food by no mistake. They can be snappy too. They will get your rings or anything shiny with their beaks right away so you have to be on top of things and paying...
You want gray chickens that lay brownish eggs correct? It is not a given but I have three Swedish Flower Hens and they are sisters that came as a day old from the hatchery but they have different feather coloring which is all a shade of gray mixed with other various colors and very pretty birds...
