Duff eggs

[Guest devonred]

Paired 2 Jan aardan together 5yr old  cock to a 7yr old, Laid 3 rounds now but not 1 egg hatched??? Eggs filled but just don't grow. Could the cock be infertile at that age?

You've answered your own question "eggs filled" =cocks fertile.

the cock or hen should not be in-fertile at that age,,,, i would suspect this infertility, is because of a past or present, ailment,, most common for this would be paratyphoid/salmonella,,,,,especially with three rounds

[showman]

If eggs are full as you say, both cock & hen are fine !!!

[OLDYELLOW]

or could be eggs have got chilled as its too dam cold

[jimmy white]

paratyphoid can produce, fertile, but" dead in the shell"

ckilled i would say i have had a couple of pairs with just one hatching, its not natural for birds breeding in the hard of the winter as we are having now,

[Guest devonred]

It WAS (past tense) a pair that was loaned to me, the only pair i've had a problem with. they looked in perfect health

[jimmy white]

i dont want to sound alarming devon red, but it does seem strange this is the only pair you have had this bother,, old birds that have this, or carry this para, can look perfect, but can render" dead in the shell" eggs,

off course there could well be other reasons, cold   , unsettled etc,, but i would tend to make some enquiries from the lender, and try and find out if he has ever had bother with this
