Ok, I have had chickens for over 4 years so you’d think I would have this sexing thing figured out by now. I adopted 4 chicks from Tractor Supply 5 months ago. One is already laying, one is getting ready to, one was taken by a fox recently and then I have this black sex link. At least, that’s what the bin said. She has not started crowing nor squatting for me like my other pullets, has a visibly large comb and is taller than all my other hens. She was just now hovering over one of her friends as they attempted to lay their first egg, and she’s always last in the coop. I see some rooster like feathering on the tail but not sure about sickle feathers. Please advise me about this perplexing chicken!
