Our 4 year old sturdy Australorp has slowly become less active and now she's not eating. Her comb is bright red, and she does come in/out of the coop with the others but then she sleeps a lot. She ran out to eat some scrambled eggs we made for her yesterday, then back to napping. Her crop is empty (not impacted) and I don't think she has a stuck egg (but I'm not experienced). No tail pumping, but she is breathing hard (I think?). We just moved, so hadn't given them any medicine for 4 months. They have the coccidiosis medicine in their water now (though I'm not sure she has drunk any). Haven't seen her stool either. Not much to go on, I know. Could it be worms if she isn't eating? Anything else I should check? It's Sunday so not vets open today.
