The temps are plenty warm during the day and are in the mid to upper 50's right now for a low. They are 3 weeks old and really have outgrown their brooder, which has been in my shed. I took a dog kennel and with very heavy duty bungee cords that are super tight attached an open dog kennel to it as a run (all this is just till they get big enough to be put in the run with the chickens (even with a divider I don't trust it to keep them in and away from the chickens). I'm mainly concerned as we have some strong thunderstorms coming tonight and though there is plenty of room and lots of cozy shavings, I worry the storm may scare them, but they may be scared in the shed too I don't know. Ever since I startled my Cayuga what looked like nearly to death, in concerned about her getting scared. They haven't been through any thunder and strong rain yet. Here is the crate and doghouse set up. Food is inside water right outside. I also drilled holes in the plastic floor of the kennel and zip tied it for a roof to keep out the rain even more. I also just built that pvc pen completely covered for them during the day so they can swim whenever they want without me having to always be outside.
