I have 8 RIR chicks that are about 5 1/2 weeks old. They have been outdoors for the past 2 weeks since the weather's been in the 60s & 70s and they are doing just great. Their coop is a converted shed, that's 4x8. We put in a roost that's about 18" off the floor. Last night, I went in after dark to check on them & they were all roosting on some side brackets that are about about 4' off the floor. Tonight, one was even roosting on a piece of wood that I put in to hang their nipple waterer from, and it's 5' off the floor. They are getting on the roost & then flying up higher. There is another shelf in there that's about 6' from the floor and I'm guessing that they'll all be on that shelf pretty soon. I really don't want them up there since that's where all the electrical connections are. The other 4 chicks are on a similar bracket on the opposite wall. While I was taking this picture, one of those flew down from the bracket to the roosting bar, walked across the roost & flew up to the bar that's holding up the waterer. I was planning on raising their roost to about 3' when they get older, but it seems like the current low roost is too low right now. When they are fully grown, I don't know if a roost higher than that would be good for them. I was planning on clipping their wings when they get older, since I will probably let them out of their run occasionally & don't want them flying all over the neighborhood. I live in the middle of the city & the dogs next door would love to get at them.
