I have a GL Wyandotte that is sitting on five turkey eggs. This is her first go at being broody and has done it like a pro. I know it takes 28 days to incubate the poults and 21 to do chicks. I noticed today that her bright red comb, wattles and earlobes are very faded. This has just kinda happened. Today is day 21. Is this some kinda sign that she is done or is it natural? I wonder if she will know if they are good and stay on them. I don't know if they are good or not, just assume. I have not candled them or even really looked at them since she started sitting. I know they don't stink.
