There are also breeds like this. The secret is not to buy from a US hatchery but to buy from the country of origin.Canadian back yard
But I take the point. It’s just that my options are limited here; I suppose if I didn’t give a thought to biosecurity I could buy chicks/eggs from all over, but I have preferred to go with the large hatchery option where there is some oversight , it’s not perfect but the best option for now. I’ve been to a couple swaps and was appalled at the condition of the birds, the containers and the sellers. Judgy? Yes, but if that’s all you have to go on.....
And there is zero chance of a feral chicken EVER finding her way here, I dont even have many wild birds lol
The Marans here for example came from Marans in France and they been excellent. Just ask Fat Bird here who will be 10 years old next month.
