It doesn't work for all breeds, and you only have a window of a couple days to look, like a week to 10 days old. And I THINK, and I could be remembering backwards, that hens have the tail feathers in the age range. Cockerels get theirs later. But it's been a while.
Here, wasps are going extinct, which is a bad thing, they eat harmful insects…when I moved here 30 years ago, you couldn’t even start bbq before the first of many wasps landed, now, I am happy to see one every other time I bbq, and, I also kill ticks and mosquitoes without feeling badI totally understand those who choose to put the critters down. We did for years so no judgment here. With everything (bees, insects, and critters alike) struggling to get by these days, I simply choose a different path because I can. In the past 5 years, I've tried really hard to not kill anything needlessly. Except fire ants and wasps. Those (bleep) can die any day of the week.
I've got a bumper crop of them.... I'll package some up and send them to you.Here, wasps are going extinct, which is a bad thing, they eat harmful insects…when I moved here 30 years ago, you couldn’t even start bbq before the first of many wasps landed, now, I am happy to see one every other time I bbq, and, I also kill ticks and mosquitoes without feeling bad
I can't put out a single bird feeder or birdhouse without them moving in uninvited... Not to mention regular nest checks in the barn, goat house, dog house, and coops. 
I'm seriously trying to figure out if I have 4 roosters and 2 hens or vice versa. I'm truly hoping that Cheeks gets to stay because OMG, he/she is so cute. I have also named another one. It has a white stripe on its head so Stripe is the name.
