I have a 3.5yo mama silkie and her two 2.5yo babies. There used to be 3 daughters, but one of them had to be put down because she kept prolapsing. The mama silkie and the top bully daughter are basically glued to each other. The other two sisters (when the other one was still alive) always stuck together so the lowest hen (Betsy) was never left out. The deceased one would also protect Betsy from the bully. Since she was put down, Betsy is always left out. The mama and the bully stick together and the bully pecks her and chases her relentlessly. Betsy is always scared and alone. Also, all three of them have stopped free-ranging as if they don't feel safe going outside anymore with just the three of them. I've been thinking about getting one or two more chickens so that Betsy will have a friend again, and so that the chickens feel "safety in numbers" and will free range again. I really like frizzles and thought about maybe getting a couple of those. Does anyone have any advice on the best age range to get them? (1) Should I get eggs so they can be hatched as chicks and the natural maternal instinct of silkies means they will be kind and all nurture them, or is it better to get them a bit older? (2) Is it okay to mix silkies and frizzles in the same flock? (3) Does anyone know of frizzle providers in Adelaide, South Australia? (I can't find any online). Any advice you can provide would be much appreciated. Thanks.
