Natural fertility can be tricky in cochins,the heavy feathering gets in the way for the process. Plucking or trimming around the vent area can help in both the males and females . Artifical Insemination is another choice,which can be viewed on youtube.Ok newbie question... I recently acquired 5 awesome bantam cochins and the pullets just started laying and I checked for fertility and they were fertile.
I set my bator up for a test batch...I put a weeks worth in as well as a test batch of my silkie eggs (my silkies are older)... As well as have some shipped eggs in the bator....
Well ALL eggs are developing nicely even the shipped eggs BUT none of the Cochin eggs even started to develop? They were fertile....is this because they are just new eggs? Young layers? I have two different Roos so both can't be infertile?
