I stopped feeding the wid birds because they just overwhelm the yard and runs otherwise.
Wild bird droppings cause cocci to chickens exposed so have some meds ready just in case. BYC has plenty pf suggestions on it foor specific brands etc.
My Medicine kit I keep handy includes:
Vet RX ready for the sniffles and sneezings. After shpows pr expopsure tpo a questionable germ. cheep enough and well worth having on hand for a number of reasons.
Blue-kote spray.....for boo-boos that bleed to clean/protect a chicky from being pecked to death by their roomies when they see the color red. they are carnivorous and have no boundries.
Diatemacous earth for a zillion reasons. I swear by the stuff. But the bioggest bag you can fimd as it lasts forever and the imvestment is good.
Dries up damp poo/kills bugs/mites/odors and other internal/external parasites. I sprinkle on food....in coop shavings and rub onto roosts and walls.... and on the run dirt as needed.
Triple Antibiotic creams bacitracin for cuts. Don't use near the eyes.
Saline solution to wash out eyes.
Peroxide and Bandages.
Antibiotic solutions for their water for bacterial infections.....colds....coughs and more.
If you have it on hand you won't ever regret it and will thank yourself rather than panick, not knowing what to do or where to go in an emergency. All available on line in many of the livestock/poultry stores.
It never ends. Just have it all on hand or else I promise you.....you suffer mentally and they will physically. ugh............
