About the 'pullet bin' at feed stores, don't count on it!
Our worst experience, long ago, was four cocoerels out of five 'pullets'!
Right now our early May 'pullets', three cockerels out of ten, and this is not unusual.
And, the five that were all 'Sapphire somethings', not actually. Two are Mystic Marans, one Easter Egger, and two are actually whatever 'Sapphires' as labeled. At least all pullets, and can't wait to see what color eggs they produce!
Hope to see pictures of your little chicks as they grow too.
