No tails and some bald backs and other spots.

It can. If the mites are particularly bad then they will stop laying as they try and fight them. On a lower load they might slow down but not stop fully.

Does having mites cause them to lay less

Yes, it can. If they have a bad infestation of mites you'd have them crawling all over you when you visit the coop and you'd see them all over their eggs.

What are the dimensions of the coop and run?

 

[Hannah J]

The coop is about 4x6 and the run is 8x12 plus 4x6 under the coop. I haven’t ever seen mites on the eggs, on me, on the chickens, or in the coop.

I have 12 total chickens. Well 6 new ones that I added about 3 weeks ago

Your setup is a bit small for 12 chickens. Do you have cameras inside the coop (not run)?

What's their diet?

 

[Hannah J]

I have one camera inside the coop and two in the run. They have a feed from Hogs farm and feed. I also feed them treats of black oil sunflower seeds, black soldier fly larvae, and dried mealworms. They also get scraps about once a week.

My chickens are almost 2 years old and they have had no tails for at least a year and some of them have bald spots not just on the tail but even on the neck area. I have cameras on them so I watch for pecking but never see any and I’ve treated them for mites so I’m not sure what’s going on. I’m getting about 2 eggs a day from six chickens. Today I actually got 4 but that could just be from heat but I didn’t know if that had a role in what’s going on

I used permethrin. I put it on them once and completely cleaned and powerwashed the coop and put it all in the coop as well. I have an all hen flock

This looks like feather plucking, not lice or mites.

4X6 coop with 12birds is tight quarters. Likely plucking one another during roosting time.
Can you expand the coop?

 

[Hannah J]

Well, I just introduced the new 6. These are the older 6 that had these issues with just them. It didn’t start once I had all 12. It was like that for over a year with just 6 of them

 

[Hannah J]

But I sadly won’t be able to expand the coop for a couple years once we move as I will build a much much larger coop looking to have closer to 30 chickens. They seem like they have plenty of room at night, they all squeeze together even though there is still so much other room.
