Hi new to this site but have read many suggestions from here. This is my second Rhode Island Red hen that is sick. The first one passed a week ago. The 2nd one has similar symptoms. They both stopped laying a year and a half ago. They would be 3 in may. I think both laid a lash egg or two a year and half ago. Both have been fine and eating well until this winter. Main symptoms are lethargic not eating much hunchback. I isolated them at separate times. They got worse/ getting worse with comb turning dark reddish purple runny poop, quite a bit of white in it. And just today she had foam in month. No nose drainage. Just some in month and won’t eat?? Idk what to do originally I gave rooster booster mixed with food and water to hopefully help but she stopped eating and drinking. I hope she isn’t suffering. If anyone has suggestions that I can do at home please let me know. The other red hen die in about a week after having same symptoms. We have her out of the bitter cold with plenty of food and water available. Thanks in advance to any suggestions.
