Take it easy Chooks Man..,not just some Chooks in some backyard?!! That sounds a bit harsher than you! My backyard Chooks have as much space asI can give them. They get fresh grass from my neighbor (I sometimes have to scissor cut it to make it closer to the "bites" they would take if Chooks grazing in a field). I beg leaves from other people's yards even raking their yards for them. They act like children with a bursting piñata when I dump those leaves into their play yard! I give them garlic, apple cider vinegar, and other natural adds to keep them healthy. Resort to antibiotics rather than lose them. Pull yucky, squirmy black soldier fly beetles from my earthworm bin to treat them. Throw out a small bit of food grade DE covered across their yard to watch them chase it down and hold back parasite overload. I dig deeper into their play place, turn it over to keep it healthy. Hang fruits and veggies for them to jump and chase. Bring in branches and create new activity areas for them regularly. I drink my coffee with them nearly every morning. Read up on this and other sites to help them when ill. I pet them, talk with them, and brag about them. These are not just some backyard Chooks though they live on the Big City. These are My Chooks! Still love you Chooks Man. You just got my dander up a bit !
Sorry I did not mean to upset you or been nasty to you . my apology if I said some thing wrong . good luck to you . Chooks man
