My Guinea Keets are 10 weeks old. They have a big bowl that I keep full of Purina Flock raiser and each night I give them some meal worms. Well.... I keep it as full as I can since they scratch a lot of it out which then gets under their straw and then tossed when I clean their pen. I'm working on a better solution for that. They are active, getting friendly towards us, perch on the branches I gave them, drink eat, etcetera... But they feel skinny to me. However the only thing I have to compare them to are ducks, which is obviously a big difference. I think that their keel bones are way to easy to feel, but again I am comparing them to my ducks. How do I know if they are at a good weight?
