Hi! We are new to guineas this year and I was wondering when we can start letting them free range? As background: we have established flocks of ducks (divided between two 25x50 pens) and free ranging geese. We ordered guinea keets at a local feed store and then decided we might want a few more, so we put our name on a waiting at another. The first batch of 6 came in Memorial Day week and, due to the warm weather, we moved them into one of the duck pens at around 2-3 weeks. They did good for the first week, then we lost one to drowning in the duck pool, so we brought them back in. At around 4 weeks we got a call from the second feed store, they had finally gotten an order of guineas (we had given up on getting them) and we picked up another 6. At this point the older guineas went back outside and have done well, roosting in the duck shed at night. We moved the baby guineas outside during the day at around 2 weeks and full time at around three weeks. We lost one of the little ones (literally, it disappeared one night/early morning) at around 4 weeks, but they are otherwise doing great. We were surprised that the older ones took to the babies instantly and the 10 are inseparable. My question is, how soon can we start letting them out of the pen regularly? They hop the fence periodically now (a couple at a time), but we always herd them back in immediately because we don't want them to disappear on us. Are they old enough to know where home is now since they have been outside since early July? Or should we wait a bit longer?
