Thanks folks- this is Horsefeathers's mom....
Rita (the hen) is the same as she was this morning. She has periods when she seems in pain/distress, standing with her eyes closed, head trembling a bit... then she'll perk up and go running after the other chickens for a bit.
She is waddling- the whole abdomen area between her legs is very swollen and hard.
In retrospect I can see that this has been developing for a while. Several days ago I picked her up and thought, "My she is getting hefty" because her abdomen felt bigger than usual. Wish I had known it was a problem then, perhaps we could have done something? But we don't think it's egg-related..... Horsefeathers swears she collected an egg from this hen a couple of days ago, so it seems unlikely that it is egg related, doesn't it? Of course Horsefeathers could be wrong about whose egg it was. I do know that she kas not been laying regularly for at least a couple of months, and I just thought that it was her age (just turned 3) and breed (sex-link) and that it was normal for her to slow down dramatically. But maybe that was an indication something was wrong internally....????
In any case, this morning before I read not to (DD was begging me to do SOMETHING) I did put a gloved, lubed finger in her vent a ways. I did not feel an obstruction IN the vent, but could feel a very large hard mass through the wall of the vent/intestine I was in. I suppose it could simply have been an obstruction further up the tube around a bend, though.
I guess we'll try the warm bath again- but I really don't know what else to do. We have no access to antibiotics this holiday weekend
Thanks.
