Tomorrow I am going to pick up two different groups of young guineas. I do not know the ages of them, but I think they are maybe 3-4 months old. I am getting 5 keets from one person (she said they are "outside" on grass). The other group I am getting are 10 French guinea keets from another person. She too says hers are living outside in cages. I have a small pen for the 5 (4'L X 3'W) and a larger pen for the 10 (4'L X 4 1/2'W). Both pens are inside my barn for shelter. Do I need to get both groups separated or could they be combined in just one of the pens? I only plan on keeping them in the pen or pens for about a month. To let them learn where home is and also let my grown guineas get used to them. (this is how I have done it the past three years and it has always worked out fine) This information is to try to help you guys understand what is all going on and why. My main question is about if I can combine the two groups of them or do they have to go into the two separate pens?
