they are getting big and my basement is starting to really smell bad!! I have an empty 3 x 6 coop that I would like to move them into outside. I live in NY and the temps are 50s during the day and 40s at night. I am prepping them to move outside this Sunday (they will be 5 1/2 weeks old) by turning off the heat lamp yesterday. They seem to be all feathered. The breeds are one Black Copper Maran, 4 Buff Orpingtons, and 2 Blue Orpington. any suggestions?? does anyone know when I can tell male or female for these breed and what I should be looking for??
