You're welcome. My best advice is to always feed the freshest feed you can find and give them the best ventilation you can. Some people think their birds have adequate ventilation but I can tell you, they don't.I appreciate it! Thank you! I'm learning so much on this website. I got my bantam flock this past year and don't want them ever to get sick. I have a second coop and run and am going to get day-old LF chicks this Spring--my hope is to make it a closed flock after that to reduce chance of sickness. Both sources of chicks are very reputable. Your explanantion really helps because otherwise I just worry!!! I'll make sure to always try and protect other people's birds from mine and mine from others' birds.
