I’m curious why my hens butt is bare?? She’s been laying about a year now and she’s ALWAYS had poopy butt. When she first started laying, I tried giving baths/soaking/cleaning hoping she’d stop, but she just kept getting poopy butt.
Follow up- she has a bald patch on her back and has for a while. It’s more than rooster damage because none of the others look like this. I also noticed a feather pin growing in dark.
The damage on her back is from being mounted and plucked. The loss of feathers below the vent is due to being plucked and likely from always having a poop butt (poop burns).
Apply some NuStock Cream to the skin below the vent to help sooth the skin and keep the poop from burning the skin. The cream may also help deter some plucking at the vent.
Damage to the back, the feathers are rubbed off, broken and worn, those will be replaced when she molts. You can put a saddle on her if the rooster is overmating her, the feathers will grow back underneath during molt. It's extremely important to monitor skin under a saddle (and saddle fit) several times a week to make sure that there's no abrasions or cause for concern.
As for having a poopy butt all the time, some hens seem to have that issue if they are prolific layers, but it's worth a try to give probiotics and deworm her to see if this helps with the issue.
For deworming, you can use Safeguard Liquid Goat Dewormer (10%) at a rate of 0.23ml per pound of weight given once daily for 5 days in a row.
Alternatively, you can use
Albendazole at a rate of 0.08ml per pound of weight given orally once, then repeated in 10days.
Here's how to give oral medications:
