I count by breed/color also. My roosters get names after they've proven they can live here, but most hens don't get named....unless I'm selling them
. I've found folks like them to have names when I advertise them.
Main coop is Eric and Gabriel, the two boys. Two barred hens, the Rhodebar, two light Brahmas, 6 black chickens (2 aussies and 4 bcm). Those are the big girls. Then there's the blue trio, and the light blue and splash sisters. I think that's everyone.
The only other pen I really count is the littles, to make sure no one died. 1 Faverolles, 3 barred Rocks, 2 blue sex link pullets, 2 blue sex link cockerels. Then a quick 1-5 on the bantam cochin hens in the same pen (they're basically all black) and the silkie rooster Glen.
When I range the cockerels I do count them when I put them up, to be sure everyone gets back inside. 4 bigs and 4 littles and 1 inbetween, that's pretty easy.
I changed my ringtone on my new phone to a duck quacking
. About drove my poor dog nuts! Had the kids double checking the brooder to see if I'd added any ducklings......
