I got French pearl guineas from JM also (nice people). If I had only a handful maybe hand feeding would have been easy. But with thirty, they were just all over the place (skittish!). And guineas suffer from group think. What one does, they all do, especially getting excited. Mine would not touch anything other than their gamebird rations until they were about 10 weeks old. I tried millet and other bird seed blend to no avail. Then one day after finding their feeder empty I threw them and the chicks they live with some bird seed and the went bananas over it. I still can't get them to take bugs or mealworms ( the chicks bet them to it anyway). But now that they are free ranging I am sure they are getting some bugs. They sure love the grasses and flowering weeds.
