Hello, I have 12 hens and 1 rooster (ages range from 10 to 3 years old) in an 8x8 coop. My DH built a 9x10 coop. I have 6 new pullets about 13 weeks old and 3 roosters that grew up togehter. Question: I want to move the older girls and the new pullets into the bigger coop and put the 3 roosters in the smaller coop. Will the older hens have a problem with the move, since they have been in the smaller coop all this time? I don't want to stress them out......Thanks!
