Another question:
I've neglected to mention the sick hen I've been writing about has a build-up of poop on her feathers below her vent. Should I do anything w/this? Been that way for a couple of days. Hope that's not making her worse.
Thanks for the advice anyone!
That along with her pale face/comb would be a suggestion of worms. If you have some Wazine-17 go ahead and worm her. The dosage is 1 fluid oz per gallon of water. The local feed store has it and it is fairly inexpensive. Don't let them steer you to the Ivermectin, if she does have a heavy infestation the worms they can block her intestines when they die and set up bad toxins that can be fatal. Give the Wazine as the sole source of water for 24 full hours.
Wazine has Piprazine as the active ingrediant and it is the worlds most widly used wormer. The CDC recommends it's use on people throughout 3rd world countries and it is very safe. All it kills is adult round worms but as I said if she does have an infestation they need to be eliminated a little at a time. If she perks up after this we will get the rest of them later.
Usually the paleness is an indication of anemia which the worms can cause.
