My first incubator was in 1973. I was really into 4H especially animal science. There was a county demonstration competition and I decided I wanted to do something on chickens. So...after a lot of searching my 4H agent found 12 eggs for me. My father built an incubator from instructions in one of the 4H manuals. Back then we did not measure humidity or have a fan. It was made of plywood. had a light bulb built in one end and a hole with wire in the other. There was a shelf in it where the eggs went and you put a pan of water underneath it. You put a 1 and a 2 on each side of the egg so you could turn it with the 1 up at mornings and the 2 in the evening. You closed the top and that was how we made them back then. My demonstration was to show how the chicks developed. My mom got my preservative, formaldehyded (don't know the spelling) for me and my aunt furnished me with baby food jars. Every 2 days I would carefully crack one egg draining the fluid and put it in a baby food jar with the preservative. I would label which day it had incubated to on the jar and had a poster that I would then draw detailed pictures of each stage with written details. This was such a neat thing to do. When the day of the demonstration came I had 2 eggs left and I had incubated them so that they where to hatch that day. We loaded up all my posters, jars and incubator. I was so excited cause when we got there and I plugged up my bator...I noticed one of the eggs looked funny. Believe it or not... my egg was hatching. Now you have to remember this is a 14 year old kid doing this with no help other than construction of my bator. I was determined to do it on my own. My time came and I gave my demonstration and proudly showed my little chick which was half way out of it's shell. My 4H agent was so proud and he told me he knew I had a very good chance on the ribbon. Well....it did not happen. I lost to a girl who demonstrated how to give a dog a bath. I guess there was a lot more work in doing what she showed compared to my month long experiment. Anyway.,.you know how politics go. But....even if I did not win...I learned sooooo much doing this. I would suggest any parent how has a child interested in things like this or science in general to give this a try...hey...it is fun for grown-ups too!! So.....now..who else has a first time story???
