My family and I are in escrow on a new house, and so the issue. First, some background: We’ve had 3 chickens (in a flock of 7) fall ill with lethargy, loss of balance, and loss of appetite. Corid did not bring the last hen back. So, if I move my existing flock, am I asking for trouble? Contaminating the new soil with an existing problem? What would you do?
