Have kept chickens for 2 years now and they were snatched a few months back in a fox attack. We have just decided to get some more as our dd1(3) is still heart broken about them disappearing. I have been told its better to keep 3 than 2 but can't find any evidence to back this up. I would like 3 but dh only wants two as he says the last two were fine. Anyone help me out with any actual evidence that 3 is better?
