We lost one girl 2 days ago and now another has same symptoms. Walking slow away from the other chickens, went in nesting box tonight instead of on the perch with the rest. Not eating, runny poop. She does breath a little raspy so think it could be a respiratory infection? I went and bought some vitamins and electrolytes and started giving her this and mixed in the water for the rest of the girls. Up until now they have all been very healthy. Can being damp cause this type infection? It rained here for days and they stayed in the pen while wet and walked around in the rain. They could have went into the coop but did not. Also one of the girls dropped an egg in the yard in front of us today and it was small and like rubber-very strange, like a jelly egg. All of their eggs have been very strong and a good size. Any ideas, advise is much appreciated.
