there is no noles or opens in the camper it is like an air streamer camper, very closed, we took them all out of it we had two coops one my hubbie made for the peeps then when they are biger we put them in the camper coop, we had 15 peeps which were about ready to go into the big one, we took everyone out of the big one today, we went in tonight to see if all went in and they did but i told hubbie we need to put up another roost. we will go out tomorrow to figure it out.Oy! Did you google and try to id it? Maybe it was an eagle! Surprising that the big ones would come into a neighborhood like that. Neighbors near here had a red tail kill a big hen. They chased it off so it never got to eat. They have never given me and trouble, thankfully, but there are smaller ones who come through every so often that seem to be sizing up the big girls. So far they have not gone after them, but they've been pretty small hawks. Sharp-shinned was the last one. Tiny. I do worry about the Seramas, but they love being out so we risk it.
