Prior to breeding my canaries I place the hens in one of my flights and treat them with doxycycline for 2 weeks. This year I still had a pair of normal gouldians left in there which had built a nest and laid on the floor amongst some of the structure for the quail(after I had taken the nests out). I left them there for a week and then decided to dispose of the eggs as they had already raised a few large clutches this year. After reading different post on the forum of people still breeding I had some regrets and subsequently placed a nest back in the flight with the pair gouldians and hen canaries. They promptly went straight back to nest with eight eggs. I checked them this morning and as the photo shows - 7 young plus 8th egg looks good. These birds were on doxy from 14th August to 28 August.
I know this is only one pair of gouldians that have been exposed to doxy (by default) but it certainly has not impacted on the fertility. Hope this helps.

As above, I have canaries and treat them with a course of Doxy in June each year as per instructions. It is in their water for 7 days straight and you must change the water daily.
I have not had any problem with infertility in Canaries at all, and know that a number of other canary breeders do the same thing without any effect on their stock and breeding results. The birds are usually breeding by late September each year. That is a 3 month period after treatment.
I would be looking at if it was any particular breed of birds, or if they were fed any other seed or greens that may have been treated with some chemical. I cannot see the Doxy as the major cause of infertility, based on my results with canaries.

A sence of humour goes a long way sometimes guys.
Particularly with a weighty subject like fertility in our birds.
