I had 3 peacocks hatched & raised with my chickens. They were a year old in May I got them 2 hens (3years old). The hens were here about a month & the boys went in the pen with them. I thought this was great, they all stayed in the pen together about 2 weeks & something got in & killed one of the hens. So I let the other 4 out to free range like the boys had done for a while. They were all out about 2 weeks & one of the boys just disappeared! No feathers or anything just gone. Maybe a week later another boy gone. So now the other 2 are back in the coop with the chickens. My question is would they have left on there own after all that time & always being here?? Please tell me what you thing happened to them!! Thank you!!
