My comment on the wandering SS is that my SS are well cared for and I'm amazed at how far they wander. We don't have neighbors so they aren't in anyone's yard but they travel all over our several acres. In comparison I have 2 barnie mixes and 1 EE and they stay very close to a structure - coop, barn, garage. All of them live in the same coop and have the same access to food and too many treats.
I wonder if it's the curiosity of SS that makes them wander more??
I laugh because I researched this breed and read they aren't very good flyers and should be kept in with a 4 foot fence. Nope, ours fly over the 5 foot fence. Thankfully we have lots of space for them within our property.
