I also enjoy the roosters crowing. I have an silver duckwing oegb rooster and a golden sebright rooster. They both come to the back door and crow till I come give them treats. They usually bring some ladies with them. They'll go visit on the front porch also when the kids are taking the bus.
We used the water and Epsom salt. We didn't measure either one. We pulled off the scab and I kinda dug a little bit with a tooth pick to get as much of the white stuff out without hurting her. We also put some Bactroban ointment. That's used on humans for staph. It's working great, just...
I had one and he was very protective of his gals. I ended up having to get rid of him. He would charge my wife and luckily my kids were to scared to go in the fence. But you never know. He may end up being the nicest rooster ever.
