Tonight was my 7 18 week old girls' first night in their new coop. They have gone from 4x4 to 6x8, so they have lots more room. My problem was getting them up the ramp into the coop -- they were on ground floor in the small one. I tried bribing them, but they stole the bread off the side of the ramp. Finally, I cornered them one at a time and put them through the pop door. My DH blocked the opening to keep them in while I caught the next ones. They didn't seem terribly upset about it, just really leary of the ramp. I was worried that they wouldn't find the roosts (I have one at 2' and a second one at about 4'). I sat with them in the coop (it was SOOOO nice to have room to sit with them) for a little while after we closed the pop-door. They seemed to be discussing the new digs pretty thoroughly. I put some of them on the shelf with the feeder and a couple of others flew up to the top of the nest boxes. I left them a couple of solar lights so that they could see to get up to the roosts if they wanted to. So, I went out to check on them a little while ago, and there they were, 4 on the east end of the 4' roost and the other 3 on the west end of the same roost. Can you say overprotective mother? http://picasaweb.google.com/sharol46/CoopProgress# is where the pictures are of the coop progress.
