I have 5, 7 week old young ladies in a super huge wire dog pen in with my others. They can not get to each other. I am wondering when I could mix them, (the other 3 are 1yrs and 11 guineas that are the same). I do let them run around the pen when I babysit them and the only issue is when there is something that they think they can eat and the chase begins. My other concern if I mix them is the food, I don't want them to lay prematurely. Any suggestions would be appreciated!
