That’s what I thought. My poor girls. They are definitely red roost mites as I checked tonight. Every 3-4 days will be be necessary to break the life cycle. I’m considering breaking the coop down and replacing the roost bars etc.
the second photo of plastic material is a black trash bag outside my coop next to some exposed straw bails I will be burning. The little white specks are either another type of mite or eggs but strangely they appeared after a couple of hours during the daytime next to some straw?
I really feel sorry for you and your chickens Don’t blame yourself for not knowing. We all make beginners mistakes. I was ‘lucky’ to read a lot shortly after starting with chickens. Because I had a few chicks dying just a week after buying them.
Next is my way and maybe you and other readers on this thread find something useful in it.
The first mite experience came the second year having chickens in my prefab wooden coop with self build extension/roost area. I discovered (monitoring weekly) the mites and a clutch of mite-eggs in a very early stage. They disappeared with cleaning (twice) and applying diatomaceous earth.
This year (after 8 years) I had my second infestation. Cleaning and applying DE on ‘touch’ surfaces and in their sand-bath area in combination with monitoring the roosts with cookie/biscuits rolls wasn’t enough this time, because they entered the nest boxes with chicks (shavings/hay?) and had spread more than the first time.
Cleaning twice, heavily smearing DE, buying supplements to make the chick/chickens blood disgusting for Red mites got it down to zero, 1 or 2 small and alive red mites daily with controlling rolls on many spots (in the nestboxes too). The control rolls are safe to reuse after 20 sec in the microwave. With an elastic band or tie wrap you can tie them under a roost.
Because I was leaving for a summer vacation I bought Permethrin to spray into some cracks I didn’t trust and to spray one of my chickens who was a stubborn broody and didn’t lay.
Not absolutely sure, but there weren’t any mite in any of the control rolls for 4 days when we left and it seems its under control now. The neighbour who looks after the chicks/chickens promised to monitor every 2 days.
DE is worthless. It can actually cause them skin irritation so stop using it.
This is not true for prevention, with constant monitoring and the use of supplements IMHO. But I wouldnt trust it enough with a mayor infestation too.
Permethrin is forbidden where I live to use on animals in the food production chain. But we can buy it for ornamental birds and pet rabbits. And because it’s poisonous, the pet shop owner advised to discard the eggs for several days - a week to be safe. The idea to apply it on the chicks was a no go for him.
