Really sorry for your losses. I know it's tough.I have been having issues with Coons eathing the chicken feed the last week, so i put the feeders inside. Well this morning i went to let everyone out and on my 3 month old pen, there was feathers every where. Opened up the coop and two dead cochin and one missingLooking around the only way it could have gotten in is at the top of the coop is a vented area, but it is no larger then 4 inches by 6 inches. There where feathers around that area so he had to have gotten in that way, killed two and took the other one off. I am so mad at myself, should have put wire on the vented area especially since i have been seeing and having coon problems. There was a buff bantam cochin rooster and his girl in with the 3 month olds, The coon got to the rooster but is he still alive, but looks like on his left ear there is a puncture wound so he probably lost his hearing. Anyway I have him isolated right now.![]()
So the rest of the day will be putting up hardware cloth where it should of been in the first place and making sure all doors and windows are coon proofed on all of my coops.

Fishmox is the same thing or go to your regualr vet and exlpain that u don't have an avian vet and he or she should sell you some. Merricks manual might also have the dosage for chickens. Not sure. I've been going by this and it's been ok. If anyone else has any input on the dosage, by all means go ahead.
