I have 4 birds 26 weeks old and have just obtained two 18 week old silver laced Wyandottes , I did as instructed and placed the new birds in the coop for quite a few hours and then slowly opened the door and they came bounding out , my existing chickens are very unhappy about the newbies and I can't get them to integrate at all , there isn't much aggression it's just the noise and I'm beginning to worry my neighbours are going to lose it with me , they don't mind the general noise but half eleven at night it's even grating on my nerves , is there any advice on trying to get them used to each other or do I give up and have the new girls in a separate coop/separate area ?
