How old? Will the extra calcium affect them? I wondered because if they are seasonal layers, why would they need layer all the time?
I mix for my bantams because 9 out of the 14 are boys and the extra calcium is not good for their kidneys. Keets are not out yet with everyone else. I'm really hoping we can get them coop trained.
Mine are now 16 weeks old. I worked for a vet that practices avian medicine as well as livestock - he's the one that said plain layer ration is fine for guineas, because most of their diet will actually come from ranging on plants, bugs, etc - the feed is actually just a backup (he used the term "supplement" as he knows all our birds range on the yard and garden).
