Can you tell me or show me what type of mesh veggie bag? Do you mean like a used onion bag? Where could I get bags like this? I tried my best to separate by breed with bird netting "walls" taped to the sides of my incubator.. it worked ok, but I could only separate into 3 categories (I had a 42 egg incubator ) If I attempt single matings, I will need many little mesh bags.Breeders that hatch large quantities of chicks use cabinet incubators that can hold 200 up to 500 eggs at one time. These cabinet incubators also accommodate wire baskets so you can group eggs by hen.
Hobby Breeders that breed on a smaller scale use incubators that hold 25 to 50 eggs so wire baskets are not really an option. Instead they use mesh vegetable bags to group eggs by hen at lockdown.
Regardless of how many chicks you hatch each season you must tag your breeders for easy identification and diligently take notes on all your breeders (good / bad qualities) so that when chicks are hatched they are tagged (wingor leg bands) accordingly so that you can easily track their lineage.
I love taking notes/photos/ documenting. LOL so this is right up my alley!
