Hi there... We have 34 leghorn chicks who I am not sure what to do about. My husband mistakenly mixed the electrolyte mixture that our feed store recommended putting in their water 4x more than the pack said to. They seem to be seizing but slowly getting out of it...the ones that might make it through it. Many of them have died. Should we cull the remainder of them that seem to be sick or allow nature to take it's toll? Help!
