I would try that, for 7 days this time, quarter inch twice a day. It's important to not skip a dose.
Here's how I give chickens meds:
- Kneel down and place the chicken on your knee, holding her still with your non-dominant arm.
- Pick up the medicine in your dominant hand (I squeeze out the monistat onto my finger).
- Using your non-dominant hand, pull down on her lower mandible or wattles to open her mouth and place a finger inside to keep it open. If she struggles, make sure to keep her secure with your arm and keep your finger in her mouth while holding her head down and covering her eyes with your dominant hand until she stops.
- Slip the medicine onto the back of her tongue, or, in this case, scrape the cream off of your finger into the corner of her beak.
- Close her beak and let her swallow
Since you will be doing his daily she will get used to it and likely won't struggle as much the more you do it.
