I have 2 pet hens who are not eating, are lethargic. One has pure liquid very foul smelling poo. The other one is holding her neck a bit odd and shaking it almost like she is trying to dislodge something. Every now and then she stretches her neck out and sort of gasps, though she seems to be breathing OK and she is not gurgling.I massaged her neck and crop (it is empty) I gave her some water with a syringe and she did swallow some. They are just sitting under the heat lamp, not wanting to move around and hunched somewhat. Both have ruffed feathers, no interest in food. I have some clindamycin here, could I try a bit of that in the event the event they have a bacterial gut issue?? They are separated fro the other 3. They'll be 5 years old in July and they stopped laying 2 years ago. They used to be free range until the Borough (who first said chickens were OK) changed their minds and said no birds, so they are hidden behind wooden fenced 16'x16' pen and they have an enclosed coop as well. There are 5 total hens, all same age. They eat a mix of whatever greens grow in their yard area as well as kitchen scraps and scratch, layer crumbles(had a 60 pound bag to finish before I got non-layer). I cook eggs, rice as well. They snack on sunflower, cat food (as occassional treat), mealworms(dried). They were wormed last summer but I don't know how well it worked. The tractor supply sales girl was kind of useless with helping me get the right product. Any ideas would be helpful. Addendum: I checked them just a bit ago and the one with the smelly poo is doing much better. She is up and walking around and her tail is up, no ruffed feathers. She even ate a bit of scrambled egg I brought down and some greens....not much, but she showed interest and ate. There is poo around but small piles, still very liquid though a bit more white/gray and not the black nasty that was there this morning. The one with the neck is not ruffed but not interested in food, not walking around much. I got some Clindamycin in her (a very small amount) and I got some mineral oil in her in case maybe she has something lodged....perhaps that will help it slide through or out. I can't feel anything but who knows. She is still stretching out her neck now and then and opening her beak like she is taking a gasp......she does not seem to be in distress....mostly just lethargic.
