Well, so the latest is that the birds "let themselves out" yesterday. After all my delay somehow the door fell open and the 5 adults and about 26 of the 39 young birds took off and started foraging as one flock. I scared the remaining young birds over into the smaller part of the loft and locked them in so I could keep them in but still leave the door open so the escaped birds could return. The adult guineas were seen to be trying to get the younger birds to fly up to the loft...much too early to roost but maybe just to teach them how to do it. My big fear had been that either the older birds would leave and go back to the neighbor's or worse...they'd lead the young birds over there with them. Instead the older birds put themselves up in the loft to roost but the 26 young birds did not return. I wandered all over with a flashlight and couldn't find them anywhere. Luckily, they all showed up this morning (I might have lost a few but I couldn't seem to count them) and all the birds free-ranged all day. I spent the morning building additional free-standing perches to "stair-step" the young birds up into the loft. I was worried that they were a bit too fat and unconditioned to fly up to the main perch that leads into the loft. I waited until I felt that they should have roosted before disturbing them only to find zero birds in the loft. Instead of the younger birds following the older, more experienced birds the older birds had followed the clueless young birds and were smack-dab in the middle of a field as the darkness settled in. I herded them over to the barn where the older birds seemed to very meticulously use the stair-step perches as if they were showing the younger birds what to do despite the fact that they have no trouble flying up to the main perch. The young birds apparently really were too fat and unconditioned to fly up to the main perch from the ground (about 8') as a few struggled to try it. They very slowly moved up from the ground to each successive perch but eventually it got too dark for them to see and some of them were stuck out on the perches and appeared to be settling in to roost. I managed to pluck a few up by hand and put them into the loft. Then I turned the lights on in the barn and herded the last 6 or so into the barn. I turned the lights off and had to try and keep my flashlight beams from giving them a chance to use the light to find a hiding spot. Eventually I found them all (there's a lot of stuff stored in the barn so they weren't all that easy to find once they had scattered). So, tonight they are all in the loft and since I'll be out of town for a few days I locked them in. When I get back I'll try letting them out in the evening so they don't have time to roam too far and I'll just have to be there as the sun sets to make sure that they are on the right track. Eventually they should figure it out.
