My guineas are a year old and all I got was an egg about every week for a month totalling fifteen all summer. I have four females and a male in a pen that doesn't get a lot of sun. Is that why they aren't laying. Someone said they are supposed to lay about an egg a day in the summer. I just thought guineas laid once in a while when the weather's the hottest.
I have 4 hens and lots of eggs when I find their nest they lay in their pen and when they free range. They prefer to free range. They can turn their egg laying off when I don 't let them out. I started out with 15 guineas I now have 36! I have an incubator.
