I am unsure there exact age but they are under a year old, I think one is a male and one is a female in the purple. The first three pic's are of my Original two, What color are they called and what do you think about them. Thanks
The first two are a Pearl (the darker one) and a Lavender (the lighter grey one).
As far as sexing, guineas are notoriously hard to sex.
You can try listening to them. The females will make a two-tone "buck-wheat, buck-wheat" noise. Males cannot make this noise. Both sexes can make the loud screechy guinea noise.
Do you see the size difference of the head gear on the two purple ones? I do think they make different noises but I can't tell, there so loud as it is.
The wattles often look different between the sexes. Think of them as 'car doors'. If the car doors are open, I suspect male, if the car doors are closed, I suspect female. Also, the helmet horn thingy can be pointier in males and blunter in females. The most accurate sexing is made according to their calls. Check out some videos on youtube of guinea sounds to help sex them. Guineas over a year old are much easier to sex.
I believe the color on the last 2 is royal purple.
The only way to tell for sure is to separate them if you can, and wait for each to call out. The female is the only one who can make the 2 syllable call, and you can look up "female guinea call" on the internet and get the sound - unmistakable once you've heard it. Wattles and casque sizes are sometimes accurate, but not always - and let's face it, you have a 50/50 chance of being right anyway.
I had a female who was so quiet, I had no idea whether she was male or female until I saw her lay an egg. Pretty definitive . She remained quiet - even for a guinea!
The third pic of the royal purples with the barred rock type hen the purple who is facing you looks like it is calling like a hen would the first pics are a pearl and lavender
