Agreeded I had three leghorn of 6(?) do this about drove me bonkers! I'd remove one and the next would step up. Remove it,here we go again,,and so on. If it's possible in chicken world to be a hermaphrodite they are the ones. Took a year for every one to settle into what they where "gonna be" I won't ever buy them again,not once have they cooperated for me! I like to enjoy my chickens not feel so confussed& misinformed. Just my two cents.
I adore Leghorns since I grew up with huge flocks of Babcocks as a kid and my uncle also ran an egg ranch with Babcock Legs. They are dynamo layers. I decided to add a White Leg to my little backyard flock and then another Buff Leg. Within 3 yrs the White Leg went bonkers on the gentler chickens and the Buff Leg went totally cannibalistic after only 1 yr. It was disheartening to re-home those lovely girls but they really couldn't be mixed with our calmer timid breeds.
