So, my RIR pullets are almost 7 weeks old and out in the coop and run. They will start free-ranging next Thursday. (I wanted to give them 2 weeks in the coop and run to know where home is). I now have 4 Barred Rock and 3 Silver laced Wyandotte pullets that are 4 days old and in the brooder til about 5 or 6 weeks old. I am hoping someone has some words of wisdom as to how to bring the new ones into the coop/run when they are correct age and still alow my RIRs to free range while keeping the new girls in the coop and run for at least a week till they free-range. Any ideas? Should I keep the run door closed so the new girls can't get out? Will it be an issue if the RIRs that are free ranging want to come into the run/coop during the day? My plan is to keep a feeder and waterer outside of the run and coop for the ones free-ranging and of course to have feeder and waterer in the run for the others that aren't. I do not want to put and food or water in the coop itself. I lock up the chicken door of the coop at night and open it first thing in the morning. The chickens just go in to the coop to sleep. Or is it ok to jut let the new girls free-range right out of the brooder? Will they follow the older chicks clues of when to come in the run and coop? The thing that worries me is keeping that run door closed....in case it starts to rain or they need to seek shelter for some reason. Anyone have any ideas on how to make this all work. Any input would be greatly appreciated!
