I have mine written in a notebook that is ONLY for my birds (its a 5 Subject notebook), One subject is for my budgies, One is for my Tiels (since that's all i'm breeding right now)
I have the parents names and mutations written on the top line one on the right side one on the left side
Then I have "Egg laid", "hatch Date", "band Date" "band #" (if I pull them to hand feed them i right that beside their info in the column)
And then under each topic I have the dates of each thing
Then I went to drsfosterandsmith.com and bought Breeding records (10 for like 1.49) and hatch certificates (same amount and price) Haven't used them yet though I've been making my own Hatch Certificates
But also in my notebook, like for the tiels, on the yellow divider for thier section I have "cockatiel breeding" 08 then my band info, From color, and what is on each one (except the numbers but i have 1-25 because that's what i'm on right now)
