One of the SFH roos I'm looking at seems to have a rose comb? All the other roos and hens seem to have a single comb. Is this normal to have these sort of variations?
I've tried to post pictures and BYC isn't letting me currently.
I would be EXTREMELY wary of that being a SFH, unless perhaps they have a really good reason for him not having a comb...like frostbite. I say that because it does appear one of my guys is going to lose almost his entire comb, but I still don't think it will look like a rosecomb. So be careful. A photo would be helpful.
Any LGD breed does not mature until at least 2 years of age. They are in need of supervision and training up to that point..............and some will take longer, and some will take less time. Males generally take longer than females, as a general rule of thumb, and like any rule only applies quite generally.It's a "big breed" type of thing that doesn't just apply to LGD's. Ideally, an LGD will be trained by it's parent(s) to the correct behaviors in a working capacity. When you don't own the parents, or an older dog to train the new pup, then you have to be the parent. For as long as it takes.
I've been employing LGD's for many years here, couldn't run this ranch without them, and they are paid well for their efforts.There are many working in different capacities that are assigned when they show me their particular area of expertise. No LGD gets a permanent job here until they have passed the 2 year old mark, or more, depending on the individual dog. We all have our own methods of raising these dogs to work, just keep in mind that if you set the pup up for failure, it will fail. Try to make every incidence as positive as possible.................and maybe find a way with fencing/electric fencing to keep pups from having direct access to live birds until they can understand that the fast movement of birds is not an invitation to chase/play fetch with.
LGD's raised well are the most awesome beings!!!!

Oh, I know all of that

Everyone I know says they have had more trouble with their female LGDs pestering birds and just in general. Mine seem to be like that as well...I have more trouble with her thinking up "games" and getting into things and just being more needy than my boy. He seems to just be along for the ride, lol. A friend of mine has described her female LGDs as divas, lol. They are great dogs, and I'm already thinking ahead to when I might add a third dog, perhaps an Akbash or Anatolian, in 3-5 years.
