It's really ok. Last year was chicken hell for me as I got bad chicks (some came to me and spread CRD throughout my whole flock, and now I think someone gave me pullets that had Mareks), so I was planning on letting my flock fizzle out anyway. We're already down from 18 chickens to 5 LF and 2 bantams (minus 1 if Francis doesn't get better) after some mystery illnesses and predators, with a couple chicks on the way. Once this round is gone I think that'll be it for awhile until we can start fresh with birds from a good source.
I've learned to not get too attached to them, but to just savor the time I have with them. It sucks but well, not much I can do about it now so might as well give them all I've got
