We have a dilemma! Wife has been taking care of a neighbor's 2 senior hens for a couple of years, letting them out of their coop in the morning and cleaning their coop and spoiling them with snacks. We have decided to have our own flock and will have chicks delivered about March 28th. Will have about 8 chicks. Our problem is that the 2 old hens, at least 11 yrs old, will suffer greatly when my wife stops "mother henning " them and their owner is the sole care giver. His attitude towards the girls is basically to ignore them, minimal contact, minimum everything. We really want to sever our relationship with him in regards to his treatment of animals but will feel badly if we abandon the old hens. He recently introduced a young rooster which is another story in its self. The rooster is a mean one and he attacks my wife and torments the old gals. He will NOT be considered for adoption! SO, we are considering bringing the 2 old ladies into our new family but are hesitant to mix new chicks and old hens. Worried about introducing disease and attacking the babies. Chicks are coming from Meyer. Our coop/run is under construction and is 6x10 and 10x24, fully enclosed and, hopefully, predator proof. What say you about this mixing of ages if carefully supervised? Thanks in advance for your advice!
