Good idea to treat the broody and keep her and the chicks/chickens away from the infested area.I will try to give them back to her after they hatch and I’ve treated her
Do you think she’ll take them? How do I best introduce them?
I might move them all into a large box because the mites are probably living in the wood
A have a very large box (fridge or bigger size)
The mites have laid mite-eggs in the cracks. The mite-eggs will come out after treatment. Repeat a few times after 7 - 10 days. Or ‘paint’ all surfaces with DE. DE doest kill the adult mites but it does kill the nymphs coming out of the mite-eggs. And keep monitoring with control rolls (ribbed paper rolls).
There is a risk the broody stops breeding in the new box. Replace her best after dark/during the night.
Introduce the chicks under the broody after dark/during the night also.
