Your federation rings in stock, and on the right bird.
Register the closed rings you order from your federation, ring chicks from a batch in a few clicks and see which chicks still need a ring.
Add each batch of rings with its federation, country, year, ring size, breeder number and serial range. A stock bar shows how many rings are used and how many are left.

Each batch keeps its federation, country, year, size, breeder number and serial range, plus notes for your own reference.

On the bird form, pick a batch: the next free serial and the ring size are filled in and the full ring number is composed for you. Serials outside the range or already in use are refused.

Your dashboard counts the chicks that are past their species' ringing age and still have no ring, so none of them slip through.
