I just noticed lately that one of my 2 guineas has a blue waddle under the neck. Not like the ones on the cheeks. Does that mean what sex it is? She does the buck wheat sound all the time like the older one (without the blue neck waddle). And after a few months is it to late to tame them to be petted and come to you? The only problem I have with them now is they like the neighbors flower beds. I can't afford to put a fence along the front of my place which is an acre. Thanks for any info.
