I'm new to raising chickens, my husband and i got the coop all ready and we have 2 roos and 1 hen in there now, they are about 10 weeks old. I have 25 pullets that will be 5 weeks old on the 22nd, are they old enough to put in the coop with the bigger ones? (the coop is really secure) i let the older ones roam free during the day, can i let the younger ones roam also? and if i do will they come back to the coop? Thank you so much for all of your help. I would like to move them out of the garage soon!
