3 of my 5 White Leghorns' combs and wattles have really grown and reddened over the past few days. I think they are around 16-17 weeks old. Do they look that age? I don't know what to look for to tell if they're ready. I have the boxes cleaned out, I just have to put bedding in them. Should I put bedding in the boxes in a couple of days if they look close? The other two are still "bald." Fiona, she's had a large comb and wattle for weeks, it finally got red a few days ago. Amelia, the third oldest. Clara, the second oldest. Her and Amelia seemed to have grown there's over night!
