It is Jan 2016 in Mountain Home Arkansas. Night time Temp's are running 15 to 40 degrees. One of my hens is setting on an egg. This is her first time. Can she be successful hatching and caring for her offspring in these cold temp's?
That is not really that cold compared to my climate and they may be fine without any intervention. If you have your birds using a nest bowl I would be tempted to try my method only after they are too large and hard to incubate for the parents. if you are not using a nest bowl I would let mother nature take it's course pigeons do not like their nest to be disturbed and may abandon the clutch. Worst case scenario you loose one squab.
This worked for me and my winter nesting pigeons it is operating for me so far at 100% efficiency. I live in Canada (we have winter and cold temperatures -40º.)
We were having a flood of Arctic Air come in and I had nothing to loose I thought.
I took a chance and moved nest bowl and all into this modified Styrofoam cooler when the squabs were getting to large for them to be incubated by the parents. It paid off in my case (sometimes you are not lucky when you disturb a nest you must keep in mind).
