Remember, she is just a puppy and will need training before she is ready to be with the chickens 24/7. Even LGD's go through puppy bad behavior. Be patient with her. She is in reality just a baby.
Ack! So, it seems that the puppy I was going to get in the next few months turned out to be a male! But - there was one female from the last litter and the person who was supposed to come get her changed her mind. So - tomorrow, I will have my puppy! I am so not ready or prepared... Her name will be Fern, she is 10 week old and a Great Pyrenees
So - what do I need????? I am going to get:
Leash
Collar
Tag made with my phone number engraved on it (PetSmart does that)
Plastic swimming pool for her to lie in/next to
Bag of food she is currently eating
What else do I need???
She is going to sleep in the chicken coop with the chickens during the night and be in the little fence with them during the day. I am glad tomorrow is going to be a little cooler. I want to walk with her a few times a day around the entire perimeter of the property on leash/collar so she 1) learns to walk with a leash and collar 2) learns the boundaries. This will give me good time with her to train and praise.

I have my LGD out roaming free now. He doesn't hurt the chickens if they get out of the pen and he protects them from predators. But, I have lost a few to him when he was 4-5 months old, because I had him penned up with the birds. It was a pen that was as big as a city back yard. At first, he didn't bother them, but then one day it started, and I lost chickens every day for 2 weeks before I figured out what was going on. He was bored and needed to patrol. He wasn't TRYING to hurt the chickens, otherwise they would be torn apart and bloody. He just got excited when they got excited and got them cornered. Then, he started "grooming" them which ripped their neck feathers out and also ripped open their neck skin. They are great dogs, though and will serve their purpose well if allowed to do their job. I hope your puppy is as great of a dog as mine. I LOVE this breed!
