Don't know if it is applying in Maine, but apparently in NJ they are having their worst pollen in written history, tons of folks lining up at ERs for respiratory problems. Know our car is coated pretty well in the mornings, been so dry. Could be your Buff's problem, maybe she has asthma! Can you give a hen a little misting treatment or would it give them more issues?
Shame about the NH birds. What is wrong with people, are they really that selfish that they would try to sell sick birds? Would never in a gazillion years take any bird anywhere if even one was showing signs of illness.
Sorry about your goat. What DID happen? We have a guy here locally who raises and breeds Nubians and you cannot go to visit his goats unless you put on booties and wash your hands prior. Although he is totally free range with his birds, he is meticulous with possible diseases and infections, and certainly respect him for that. He raises some absolutely gorgeous animals and accordingly gets top dollar for them, as he should. He is always at the Unity Fair, among others.
Bad experience with duckling hatch. 2 beautiful Pekins burst out happy and healthy. Were in the box next to the wood stove that night after drying out. While moving them, the last egg that had that night to go yet before hatch rolled out and crashed to the floor. Blood. Pushed it back together and back into the bator. Sure it would not survive, but was alive at the time. Overnight my cat decided the 2 ducklings in the box altho covered with a screen, were playthings and found them dead, laid out perfectly, not mauled, in front of the woodstove. He has never done this before, ever. What is it with our bad dogs and cats these days.
Meantime, the damaged egg hatched out, her yolk was still attached to her belly, just let her be in the bator with plenty of moisture figuring she would never survive. Here she is at my side in a box with the space heater and being an absolute brat, she has already bonded to me and wants attention all the time. Eating and drinking like crazy and trying to jump out of the box to get to me. Will keep her real close and that cat knows he's in deep doo-doo and won't come near, but now the dogs are super curious atho have introduced them and assured them it's not a big deal. Gave her a rubber ducky which seemed to calm her a bit, but she just wants me. Poor thing, she's all alone and don't want to imprint her so much she will only want me, but she just looks at me with that sideward glance like they do, so know I am doomed. She is one lucky bird to have survived, so guess I owe it to her. Stupid me to have let that egg roll out, but amazingly, she made it. Healthy so far and eating and drinking like a pig in disguise!
Sorry about the loss you have had with your chickens, certainly sounds like a fox feeding its kits, maybe they have grown enough and moved on, but wouldn't count on it. Why would they? Free meals and all. Would def maybe ask around, maybe someone will rent you a game cam or even offer to take care of the problem for you. A nuisance animal is fair game after all, and sure the game warden would side with you if need be. Live traps, probably not, they're too smart. But sure sounds like fox to me, and if it has taught its young, they'll be back. My heart goes out to you, went thru this too and hated to do the head count each night, always one short. You've either got to keep them penned up for a week or so or take care of the varmint.
