Current thinking is always of better use than old outdated threads, if fact I believe there is a forum rule against digging up old and or aged threads. The site always has new bird keepers, and many times they need the information, when they need it. Telling someone to 'Google It' is not really in the spirit of BYC. I offer my birds almost all of the kitchen fluids, be it from corn, beans, peas and etc. A little milk if it hits the expression date, I have a stainless steel dog dish, the type that does not tip over easily and dispense the days fluids along with whatever other kitchen scraps there. Remember chickens like meat, being omnivores they enjoy a nice steak, or what ever you can spare from one. There are a lot of small things that will add up if you just think what can the birds use from what the family does not.
Best to you and your birds,
RJ
