Kippenboertje
Chirping
Yes, you're right. Brabants boerenhoen or Brabançonne is a rare local breed.Welcome @Kippenboertje , Your hen looks like mine, which I have as a Harco, I will post pictures later. I see you are from Brabant, wasn't there a Dutch breed Brabant??
Now, funny...I set my broody on the 9th November with Olive Eggers, some Australorps and some of my eggs. I put two of the old eggs which I normally keep in the nests to show my hens where to lay. Well, today a chick hatched from one of the old eggs! Apparently this old egg was fertile and since there were hens laying eggs in that nest, it started developing. I am planning to put the early bird chick under another mama who already has chicks.
