Hi all, I have taken in two old girls (4&5 yrs.) from a friend 3 days ago. The flock they came from is local and healthy, they just dont produce much any more. They seem to be situating nicely, eating and drinking nicely, good color and behavior and all but I've noticed 2 things: they have watery poop (clear with some dark green and somewhat explosive) and one has laid a shell less egg- the other laid a beautiful egg. What could it be? I have a batch of chicks coming in May which i had ordered vaccinated for mareks and coccidosis and i want to keep them healthy of course. It was suggested in another forum that I cull the old girls but for the last 15 or so years I'm kind of known for being a retirement home for old hens. thoughts?
