we are new to hatching and thought it would be a good experiment for our kids to watch a chicken develop. I have approx 30 eggs that i got from my work on a farm to see if they could be hatched. The chickens look like isa reds, we would like to know how to candle a brown egg as they don't seem to be transparent as white ones. If anyone can help we have 3 children who have already started naming the eggs!!!!!!!!!!!!!!1
