His feather condition has been terrible the past couple of months, I haven't noticed many loose feathers around but something is definitely not normal. I haven't noticed any bald patches, but he could be more susceptible to cold because of his ragged feathers.
This seems pretty likely at this point
I haven't heard of gefilus, but we do have some avian pre+probiotics that we were adding to their water once every few days (they have always had a thing for eating poop, which is worrying). I stopped recently because I was thinking all the dextrose could exacerbate an infection (I have no idea why), but I will try sprinkling some on food as you suggest. Should this be done every day? For how long?
Every day isn't necessary. Use probiotics as a way to 'top up' good bacteria normally present inside your quail. Especially after antibiotics, during times of stress, after diet problems, and any time your bird could be overrun by thrush or bacteria, such as in the case of sour crop or peritonis. It isn't really medicine or a cure, it just re-stocks the good bacteria to help break down food into basic nutrients to be absorbed by your bird, and a lot of those probiotics will eat up resources that can be used by yeast and bad bacteria so they can't multiply very easily. After using this once a day for 2 or 3 days, you won't need to again unless the infection doesn't clear up.
Mixing it in the water at the same time as acv might retard the probiotics a little, so do those first, then at the end of the day, replace with the acv water.
Acv can be given every day, it's a good practice and many bird people use it daily! You want one with 'mother', or a live culture in it.
The Guardian angel is used to support your bird's energy and try to prevent deteriorating condition. It should only be used to get you by until either
A) you discover exactly what's wrong with your bird, and start treating that specifically, or
B) symptoms subside.
Failing either of these, I would stop the G.A. after a week, as by then it's clearly not helping.
I'll see if I can find guardian angel, and will get some apple cider vinegar in the meantime. I've given them a choice of plain water or water with nettex nutri drops in it today.
Get rid of the unmedicated water, lol. Quail don't understand how to self-medicate, they only know that one water tastes funny and the other doesn't, and won't seek out their vitamins or medication when they feel sick the way we might. If your fluffballs need medicine or vitamins, you have to administer them responsibly or you're wasting your time.
Thank you so much for all the suggestions! I'm a litle worried about over-supplementing and making things worse though, do you think just using guardian angel would be good enough? Or should I be doing ACV and probiotics too?
You're welcome! I love birds and I'm happy to help with anything I can. Yeah, G.A. would be enough on its own, but using it in combination with acv and probiotics won't do any harm. I have heard not to use the guardian angel in combination with water purifying liquid such as aviclens, so if you use any, stop until your G.A. use has ended.
Also with G.A, stop using any other vitamins containing iron! In fact, when using multiple supplements, check the ingredients for heavy metals. Really common ones are iron, zinc, copper, selenium, and cobalt. If both supplements have one of these make SURE you don't exceed 100% of the reccommended allowance.
For example, if your feed contains 20% daily iron, your feather supplement contains 60% and your vitamin mix contains 40%, this adds up to 120% daily reccommended iron and is dangerous as unlike minerals like calcium where extra amounts are just pooped out, heavy metals can pile up and become toxic. You can't stop your feed, so you would have to stop one of the other two to get back down below 100% daily dose.
If you're ever in doubt, or the amount is not listed on the packaging (HORRIBLE practice! Should be illegal!) choose one of the supplements you feel has the most important benefits for your bird right now, and don't use the other until it becomes the better option. My cabinet is full of supplements, but I rarely use more than one at a time.
