With my 8 week olds that are outside, I started putting outside in the large coop during the day, with the door open at 6 weeks old. They stayed in there for at least a week, no one dared go outside. I just really want them out of the house during the day. I'm sick of the dust everywhere, and now since they are bigger they are kicking it up everywhere. Those Silkies sure like to scratch around all day long. They only have a 60 watt light now at night, I kick it off during the day, but they are in my loft, and its super hot up there during the day. Its always around 75 plus up there, even with the AC on, it has huge windows that get sun from about 9am to about 4 pm, so its always hot up there.With mine... I keep them in until they're 8 weeks old and have lowered the heat lamp temp (I have them on an adjustable dial) each week until they can handle the outside temps. Then they go into an enclosed, wind shielded coop with an adjoining door into another vented coop. They stay there until almost 16 weeks old which is when, I personally, merge them, at night, in with the grown flocks, which some still have free range and others are in their own breed perspective coops, with runs..
So you think I should still leave them in the house? I just want to do whats best for them, and they will not be outside over night, I would probably bring them back in around 6-7ish when the temp starts to get cooler. I know they said its going to be around 90 on Sat, they are for sure going outside when its that hot during the day, LOL They will have the coop, and a 8 ft by 4 ft grow out pen run with the coop.
