Yes, they can. I lost a bantam d'uccle hen to one last year. Plus, like Raz said, they love eggs.
Nova, I seriously cannot believe someone is stealing all your produce like that. I would be beyond ticked. Can you put any fencing around it as a deterrent?
Vj, good for you! It was a great day for a run, too.
Not too much exciting here today. The chickens got to spend the day picking through the wet grass for bugs and worms. I noticed in the garden that a few of my cucumbers growing near the fence have been half eaten. I do believe a few chickens are helping themselves to some treats. I need to get out there to pick them before the chickens are out and about for the day or they'll eat them all up before I get them.
