We had a real cold spell (5 degrees at night with windchill) here for a couple weeks and I noticed that my rooster isn't crowing anymore. He sounds horrid. Is it possible that he has a cold? Ed is acting fine and his other verbal noises sound normal. Also the 2 chickens I brought home 4 weeks ago (one may be a roo but I'm hoping he is a she ) https://www.backyardchickens.com/forum/viewtopic.php?id=423316 are still not laying and Ed, the rooster, isn't looking at either one of the two. Is that normal? I have milk crates as nesting boxes and they use the dog house instead to sleep in.
