My friend (?)has house chickens and has had different ones for many years. The mayor of her town knows it and apparently doesn't care. She basically has had silkies and they didn't fly so she allowed them outside. Her dog was great protector for them and they stayed close to him outdoors. She also(for a time) had two Serama hens and didn't let them outdoors because they were good flyers.
Apparently her silkie was exposed to Mareks(from wild birds ???) and brought it indoors with her. The silky and the serama hens all died, each one a day apart. That was the end of last year. Recently she has gotten two new silkies that once again she has in the house and allows outdoors. I've had to distance myself from this because I get much more upset when they pass away than she does.
Her dog passed away recently at age 17, considering how overweight he was, that must have been at least a small miracle. She also makes a buffet of different food items and sets them out so the chickens can pick what they want. None of the items are what chickens should be eating. I discovered BYC years ago trying to find answers for her questions as well as trying to steer her to the right way to house/raise/ feed her birds.
None of this has made on impression on her or caused her to give them proper food. I also told her she should at least get a covered outdoor pen, with raised flooring (wire) so the birds could have fresh air without becoming food for predators. And not be on the ground, where bacteria etc. could affect them.
I should mention she is a non-conformist in most areas of her life. She refuses any vaccination (Covid etc.) because "doctors inject poison into your body." She also pulls her own teeth with string attached to tooth and door knob etc. As to wearing a face mask because of the Covid virus, she always has it pulled down below her nose.
We both travel on the free township senior's bus, so there is no way to avoid her. Please forgive me for saying all this. But I guess there is no way to get her to change.
