Here's my predicament, I've got 28 4 week old mostly Wyandotte chicks in my living room. My coop has no power nor is there a powered building anywhere near it. My chicks are getting too big for the two brooders they are in and the dust they are kicking up is bothering my DHs allergies and can't be doing the rest of us much good either. There is nowhere else to put them but they probably shouldn't stay in the living room much longer. My coop is fairly small 8'x8'. I have 9 full grown hens in there now. Most of the chicks are going to be sold in another 4 weeks or so which is why I have so many, they won't all need to live in there permanently. It's still in the 30s or below at night here and only maxing at low 50s during the day some days. So the questions are: How old should they be before I put them out? What do the temps have to be for them to be good out there? Will them being the size of my smallest Bantam hen be big enough to hold their own with the older girls? They way outnumber the older hens, will that help with their integration into the coop? Our set-up is not really meant for adding new chicks into the flock. If I had my way we'd send the 7 original big hens packing and just have the Wyandottes and my two bantam girls but DH really likes our original flock and we need them to keep laying while these babies are growing. Would the small size of the coop and large # of chickens that would be in it be enough to keep it warm enough for the chicks to go out a little early? It's completely draft free and just with the 9 hens it is a few degrees warmer in the coop than outside it. I'm keeping the chicks at about 75 degrees now, just came down from 80 at the end of last week. They have no issues with being at that temp and several of my favorites will spend hours sitting with me in other parts of the house where it is only 60 degrees, maybe less in the computer room where they like to sit and watch me type (we keep our house cold). I'm fairly certain that they aren't feathered enough to go out to the coop just yet but in another week they might have finished feathering out, all they really have left is their necks. So that's all the details, answers anyone? Thanks!
