With money being tight and no help available, to me the best solution to your problem would be for you and your brother to each pick two hens (the ones you like best) and sell the rest of them as soon as possible.there are a lot of problems with my run, and especially my coop. me and my brother are the only chicken-lovers in the family. i can't really afford all of this, and i am trying to be budget friendly, but apparently there's no going there. if i let them free- range, there are a lot of "sanitation issues" according to everyone i've talked to. i am thinking about just letting them free- range despite all of this and "we'll burn that bridge when we get there"
i think i sound like a horrible person for keeping 13 birds in there. i will lengthen their pen the best i can, with what i got.
Your hens are suffering. If you keep this situation going on much longer, they will get serious health issues and even die or turn on each other and develop cannibalism, the already shown feather plucking being the first step.
Just remember that in the future, whenever your finances and situation will allow you to provide a proper chicken coop and run, you can always have more hens.
