Agreed — this isn’t gapeworm. Parasite life cycles are highly species-specific in most cases. For example, the roundworm that infects chickens is different from the one that infects turkeys.
Keep and eye on her and most importantly don't jump to a treatment at the first sign of a perceived health issue - it happens all to often (with good intent). Many of these medications have side effects. Antibiotic treatment is q great example, it can lead to sour crop (kill off the good...
You acquired her about three weeks ago and she has not laid since? Was she eating/drinking then, but in the last 3 to 4 days has been reluctant? That open mouth posture makes me think gapeworm - the permethrin would not be effective. I would suggest treating with fenbendazole. If she's not...
Hard to say if it'll persist. It appears to be more of a misshapen cornea. However, it seems to be bilaterally symmetrical and without any lesions. So, her eyelid function is good - if she couldn't close her eyes there would corneal lesions. There's no discharge, so it's not irritating her.
If...
This appears to be a conformational abnormality—just a unique trait of this chick. There isn’t much room in the skull, and chickens have relatively large eyes for the size of their head. If the issue was due to an infection, you’d typically see neurologic signs like torticollis (head tilt)...
My two cents:
At 2.4 pounds and 7 weeks old, it's unlikely that you're dealing with "organ failure." That typically presents as ascites (also known as water belly), which is more common in fast-growing broilers—birds that would normally be over 6 pounds by this age.
If ascites were the issue...
I would agree
I agree with Wyorp Rock, based on the description, location, and how fast it appeared, it's likely a blocked salivary gland - with that said, I've not seen one in a chicken before. Most often, sialoceles are self-limiting and should resolve in a couple weeks. I would not consider...
I want to clarify the differences to avoid any confusion.
Safe-Guard AquaSol is a 20% solution (200 mg/mL).
Safe-Guard Suspension for Goats is a 10% solution (100 mg/mL).
Both contain the same active ingredient: fenbendazole.
Dosing differences:
Goats (ruminants):
5 mg/kg body weight...
THE DOSE CITED IN THIS POST IS 100X THE LABEL DOSE. DO NOT GIVE AT THIS RATE.
The correct dosage is: weight of the flock (lbs) x 0.00227 = milliliters per day x 5 days
The dose for Safe-Guard AquaSol is 0.00227 ml/lb. The minimum treatable flock size on the label is because it's very difficult to measure such small amounts. AquaSol is 2X the concentration of other legacy Safe-Guard products.
Is her abdomen symmetrical or lopsided? Ascites fluid is nearly the consistency of water and straw colored. This 'mucus' is clear and viscous, it appears to look like albumen. If you can palpate the abdomen, can you feel a firm mass, or is it soft?
Agreed. This is an embryo - the vessel formation is the key giveaway. It's normal for the yolk to begin breaking down as the embryo grows/is being incubated.
I'm looking forward to hearing how this works out for you. You may consider adding a few drops of iodine to the water to limit the spread. Sorry to hear your having this issue and hoping for the best!
