My first aid kit is quite substantial but partly because we also have horses and cats and many things are interchangeable. I’m in the U.K. and we don’t have access to some of the things you can get in the US and elsewhere but there are sometimes ways to source them. Key items which I’ve either used already and keep in stock following threads on here and which are readily available to me:
- permethrin spray (can’t get it for chickens here but can be sourced for ornamental birds)
- ivermectin (can buy the pigeon version)
- wormer (we only have flubendazole powder licensed for poultry so I have that but also some panacur liquid for cats, that’s fenbendazole)
- vetericyn spray
- chlorhexidine
- saline
- vaseline
- coconut oil
- medical scissors
- gauze
- vetwrap
- tweezers
- cotton wool swabs and buds
- aspirin
- Critical Care powder
- probiotics
- electrolytes
- vitamin and mineral supplement for water
- calcium citrate
- miconazole (in form of gel designed for humans with fungal infections)
- amprolium for coccidiosis treatment (pigeon version)
- bisacodyl to help impacted crop (have dulcolax for people)
- clean towels
- Epsom salts
- syringes
- droppers
Others things not easy for me to get here but useful:
- triple antibiotic ointment (one of the most useful things of all!)
- Amoxicillin
I also have a variety of bandaging supplies as an ex-boyfriend worked as a lifeguard and the swimming pool were throwing out all their out of date stock. There is nothing wrong with the items, I guess they are not guaranteed to be sterile anymore, but they’re really useful. I think you can buy out of date supplies like that on
eBay sometimes. I’ve not had to bandage any chickens up so far but it’s handy to have for cleaning wounds for example.
