After finding a surprise cockerel in my hatchery chicks, I'm starting to worry about my older chicks and if they might be hiding something from me. Einstein the smooth sizzle. She is four months, give or take a few days. She and her special extra toes started worrying me that she might be a boy when brown spots started showing up on her. Cheese the blue silkie (with our black sumatran bully and a cat photobombing her). Also four months, give or take. Are they still too young to tell, or is there enough for you guys to get an idea if they could be cockerels in disguise?
