I'm looking for like a hatching/breeding recordkeeping sheets. you know like cock: hen: band color or# how many eggs set. I'm not sure what I need yet.I need to be able to keep track of my breeding birds so I can know who is has what chicks. so I can see who the cock and hen is to keep track of what the chicks thro out and see if they are keepers or culls. I hope this is helpfle for you!

It is much easier in my opinion to make you one in excell, you can update based on teh number of eggs set, number hatched by sex, and keep and cull records for each mating. that way you know where your good birds came from as well as how many it took to get them. Some matings will result in better numbers of one sex or the other, its a great tracking tool when built the way you like to use it, rather than just an off the shelf solution that doesn't take other things you want to know into account.
The other advantage is that you can insert a photo of teh breeder birds with the information and ability to track progress over generations.
