I would use the vitamins that you have - the multi-vitamin one. If it has instructions for poultry, then it should be fine to use.@Wyorp Rock thank you! I ordered the epsom salt yesterday and it should be here in a couple of days, so I'll start with the daily soaks as soon as it arrives.
Should I continue only with the vitamins I have a couple of days a week or should I try with the vitamins you suggested instead? If I were to try the ones you recommended, should I stop completely with the vitamins I have while trying the others?
I'm very curious, do you think the amount of vitamins look correct for a chicken's needs (or in this case - 100 chickens)? I'm a bit sceptical of whether all livestock animals require the same percentage of vitamins, but I have no knowledge in that area, and these were the only supplemental vitamins for chickens at our local farm store. Do you think it looks alright or should I order something specifically made for chickens instead?
