I noticed odd, non breeding behavior in October. Normally, I breed in Dec. to have babies off Jan, 1st. Not this year. After talking to all my southern friends, I found out that my birds were not the exception. Birds were shedding feathers after Christmas, and very few, to no, fertile eggs were being produced. We had 65 degree days , and then 20 degree days. I'm a firm believer that Mother Nature sends a message to her critters, and most listen, except the very young and the stupid, who need weeding out anyway, if the species is to survive.
So... I listened to my birds. Wrapped up my covered runs in clear tarps, which I had never done before. Made a few more water heaters, and got in a load of straw, and feed.I'm very glad I did. The bottom dropped out in the South, as you all know. My birds were snug, as the tarps turned their covered runs into almost greenhouses during the day.
What do you know...The eggs collected DURING the snow/sleet are all fertile.Those eggs are due the 5th of March.NONE the week before were fertile, so I'm guessing that the last week in Feb will not be nice here.
This weather has not seemed to affect the Northern birds to this degree. This weather has been the exception for us in the South, thank heavens.Birds can get used to cold, but extremes of up and down temps sound a warning to them that their chicks would not survive. Yet all my girls laid like crazy through the extreme cold.
If anyone has a better explanation , I would love to hear it.
