Thank you to everybody who answered our Issue 2 Survey on French Moulters, here are the results:
FOR EVERY 100 BIRDS BREAD, 6.4% WILL BE FRENCH MOULTERS
Here are some of the comments we received from this survey:
 French moulters appear at the end of the breeding season and I
believe are linked to a combination of factors including the following:
 No french moult in ten years or more, my father and my son have not had any in years, or ever in my son's case, don't think it is a problem like it was when we had it every year, maybe a genetic lack of resistance, as all my birds came from lines that had it but, none that showed it were used for breeding, only birds with no f.moult were used ,so year after year there was less and less, then there was none!!!
 The number of French Moulters I breed in a year seams to be dependent on a couple of things:
A) whether or not I've brought in a large number of new birds (such as buying out someone else stud), at which I experience a large amount of french moult, around 75%.
B) How long has it been since an attack. It appears my stud's resistance goes up and down, that is to say I can expect an attack every four years, at which point about 75% are affected.
This year I've had no french moult, but the last two years were bad, the
first of the two being my time, and last due to the aquistion of a stud.
