First don't beat yourself up I wonder if Odys comb was really from frostbite? It would have been dis colored or blackish at the top? If so then it was more than likely frostbite, they bleed a lot from their combs and wattles. I saw Rocco had some on a one of the tips of his comb and he had bleed onto the back of his head some. These things happen with chickens/livestock, they are very resilient and he shouldn't skip a beat if it was small portion of the comb. Just watch for infection, you can put Bag Balm on it for a soothing effect and as a preventative in the future when it is suppose to be cold. You are doing great, you will probably figure out hatching before me! Dont worry, I know how that goes, I was a nervous wreck back in November when we got that first cold snap. We had a girl get frost bite, then a month or so later the roo's and two hens got frostbite from drinking out of the heated water bowls. Then finally a month later our roo's almost killed each other and this was their first fight. The only way to learn is by continuing what you are doing, reading/researching everything you can about chickens and asking questions here. The instincts are there, obviously you love animals, experience comes with practice and that takes time. I don't know where I would be as a chicken keeper if I wasn't involved with BYC.
