My guineas sleep in the chicken coop with the chickens. I haven't had a problem with them being togeather. That is a good suggestion that you keep the guineas in the coop for at least two weeks so they know that is their home.
Guineapeeps I found the orange zest bird seed at Walmart and the guineas love it. That is the first thing that they've tried and they like it. Thanks for the tip.
I'm glad they like it! Next time maybe Spider-Man and Mary Jane can go for another ride to Walmart and actually go inside and pick out their treats!
