So, colored zip ties, same - same. Great idea. I like this. I would assume room for growth and then cut and re-do once a month or so? These too could potentially cut into them during unchecked growth spurts.
Walt, you can't beat a good broody. But, you can't quite predict them or time them as well either.
I hatched from broodies for 4 years and then this year I had a BYC lady down the street hatch for me cuz she enjoyed doing it and seeing the strange chicks that come from my farm. My big incubator is on loan to a friend and you know how that can be....hopefully I will get it back. I have an even larger one, but my wife gets a little crazy when I run it cuz the electric meter spins so fast you cant see the black line........hahaha It is an old redwood unit that does about 1200 eggs at a time. I needed more out since we are having a national meet 3 hours from here at the end of January. I am convinced that broody babies are better birds in all ways and their natural resistance to disease is exceptional.
Yup..the zip ties or whatever you use need to be watched during the growing and cut off and replaced when getting too tight. After the bird stops growing it is not an issue, but I found that the plastic spiral wire bands are just dangerous because they have those two sharp ends.
