I've been trying to breed a silky hen ringneck for a few years with little success, most of my males were too old etc. I got rid of a few other birds (pigeons) and now have time to focus on breeding my silky. I want to get the maximum number of chicks as stock for next year before winter hits, all i currently have for doves are my silky and her mate and a really old pair past breeding age (and a few extras). i was wondering if the older pair could still foster even though their old. (they aren't that old even, they still lay and may be able to hatch, not sure i was taking the eggs away, the cock is at least 6 or 7 years old but still tries his best. But i was wondering if i stuck some silky eggs under them if they would be able to take care of the babies. thanks.
