RoseMarie1, I wonder if my vitamin and electrolyte powder can go bad? It's about a year old, but I haven't stored it in an air tight container or anything (just the bag rolled up) and it is pretty humid in my house because our floor is a concrete slab.
Cknldy, I do think that most of my problems are the hatchery problems. I just had another stop walking around (with no visible injuries on legs) which makes two chicks now with that issue.
Some other chicks do a weird waddle thing, especially my Australorp with the slightly malformed head and major underbite beak.
I bought some Australorp chicks from a different feed store who buy from a different hatchery with so far much better results.
casportpony, I am getting conflicting conclusions in my research on the acv vs calcium.
Some sources say that it leaches calcium, while others say that it draws calcium out of food and makes it more absorbable. Some say the benefits outweigh the negatives.
I would guess that I wasn't using enough acv to create a major depletion of calcium. I would find it odd, especially since I've been using 1oz per gallon acv in ALL my chickens water for as long as I've been keeping chickens, with no problems (until possibly now?)
It would be especially odd since I have added sesame seeds to my chick feed as they are high in calcium for a plant food. This is something my last batch of chicks did not have access to, yet they grew and developed fine with constant acv in their water.
I don't have anything in anyone's water right now (except the big chooks outside still have acv and vitamin supplement). I like what someone said in a different thread about not forcing their chickens to drink anything, but providing supplements free choice beside clean fresh plain water. I will be trying that and if I need a sick chick to take something badly enough, I will make it desirable with honey and offer or hand feed.
I am pleased that the chicks frmy own flock are still healthy and problem free.
