I bought 9 chicks this past Saturday that are 18 weeks old. Three comets, 3 RIR, and 3 barred rocks. Saturday they were extremely skiddish as I expected and stayed huddled in the coop and did a little scratching. I picked them up and put them out in the run and they seemed to love it, eating grass, scratching etc. They went back inside and stayed all day yesterday, temps were in the mid to high 40's. Today is in the 60's and I figured when I came home they would be out enjoying the weather. I set two of them outside and they both came right back in. A few minutes ago 3 of them came out but only for a couple of minutes. They came from a pretty large breeder so I don't think they have spent much if any time outside. I tried to coax them out with some bread and they are what they could reach from the pop door and left the rest on the ramp and ground. They've got a huge run so I don't want them to feel cooped up. I also don't want to keep tossing them outside if they don't want to be out there right now.
The last two nights I have gotten home really late and the first night one of them roosted outside on the ramp. Last two of them roosted part way out the pop door on the ramp. The remaining 7 were huddled up close and there was about 4 foot of empty roost space on the pole. I will be home tonight before it gets dark. If they are outside again I am going to block them in.
I just thought it was funny the only 2 times they went out on there own was at bed time.
