I initially had started out with 6 guinea 3 years ago. I was down to 3 before yesterday. I went and bought 4 more yesterday, these new guineas are a year old. I put them in with my other 3 adults. They seem to be doing fine, other than the one adult one was going around pecking the 4 newbies on the head. My question is this, When I bought my first 6 I had then penned up for a month, seen=med to do the trick as far as not running off. Will I need to do the same thing with these 4 or will they learn sooner from the other 3? Of course I would need to leave all 7 penned up since they are all together.
