Canary breeding produces lookalikes. A room of young birds of the same colour variety, all the same age and size, is a room where memory fails within a fortnight — and where a breeder working from memory starts guessing at exactly the facts a buyer is paying to know: who bred this bird, when it hatched, and whether it is genuinely the age claimed. A reputable breeder answers those questions from records written at the time, in the stud-book style long used by serious keepers: one entry per clutch, every bird identified by a ring number rather than a description, and nothing left to be reconstructed at sale time.
Parentage: Both Parents, Identified by Ring Number
The entry opens with parentage, recorded as ring numbers, not names or colours. The cock bird is entered by his closed-ring number and year, the hen by hers, so the chick's entry points to two individual birds whose own entries sit earlier in the same record. That precision is what makes the record worth keeping: it lets a breeder avoid pairing close relatives in later seasons, trace which pair produced strong youngsters or recurring problems, and answer a buyer's question about a bird's background years afterwards. Alongside the parents, the clutch entry notes the pairing date and the nest, and — where eggs were fostered under another hen, a common and legitimate practice — which hen actually reared the chicks, recorded plainly rather than left to confuse the parentage later. A breeder who can show you this entry for a bird you are buying is showing you a system, not a story.
Hatch Dates and the Clutch Record
Against the parents sits the clutch itself, dated step by step. The record notes when laying began, how many eggs the clutch contained, when hatching started, and each chick's own hatch date — chicks in one nest can hatch across more than a day, and that individual date is what a bird's age is counted from. Fertility and losses belong in the record too: eggs that never hatched, a chick lost in the nest, the number finally reared and weaned. Those plain figures are the breeder's working history, the basis for judging whether a pairing is worth repeating and whether a hen is being bred too hard. For a buyer, a hatch date given from a written entry carries weight that a round estimate cannot, because a canary's age governs when it should be bred from, how it is classed at a show and what a fair price looks like.
Closed Rings Fitted in the Nest
The ring closes the loop between record and bird. A closed ring is a seamless band slipped over a nestling's foot in its first days in the nest, while the foot is still small enough to pass through it; within a short time the foot grows and the ring cannot be removed or fitted. That is the whole value of it: a closed ring on an adult bird could only have been put there in the nest, so it stands as proof of the bird's age and origin in a way no later-fitted split ring can. The ring is stamped with the breeder's identifying mark, the year and an individual number, and that number is written into the clutch entry against the chick it was fitted to, at the time of fitting. From then on, bird and record cannot drift apart: catch the bird, read the ring, open the entry, and parentage and hatch date are in front of you. When the youngster leaves for a new home, that record should travel with the bird rather than stay behind in the breeder's book. Moving the record onward is simple with Transferrable Profiles from KinsLe — the profile built up for a bird passes into the buyer's hands carrying parentage, hatch date and ring number, so the stud-book facts follow the ring.
