Any suggestions as to what this may be please.
Yesterday I noticed a couple of watery/yellowy poos in the run, and today I noticed some in the run next door too. I spotted two very listless hens who are not eating and I don't think they are drinking either. I have now removed the hens to separate run & hoping none of the others get it.I brought a few new hens in last week, but they are in a different area on the property, not even in view of these sick hens.the new ones all seem fine. I wonder what I can do to help my hens recover & stop any more getting it.
