Hi, I have a coop to fit 18 hens witch at the moment has gone from 9 to 6 to 3 to now 2 , one being my lovely docile cockerel and his sweet sister . my originals are there parents 1 cockerel( Rhode island red) and 2 sister hens (Marans) witch decided to up and leave there chicks after 6 weeks and go down farm with all the grown up chickens . i need to really bring them back up home and was wondering if the two cockerels can live in harmony . i have herd they can and nether are aggressive there both scared of there of shadows! my youngster one has been in company with 3 others before all brothers and they never touched each other , as for the daddy who ran for the hills after are pint sized cockerel went for him . so just wondering if it was an idea to introduce my two mr's to each other and see how it goes and after that see if they could live together?
