He does have sort of puffy cheeks. I know it hard when they are so young.
This is going to sound off the wall but the lady at Murdoch's takes each chick and holds the legs between her thumb and forefinger. She does a whistle and the girls will sort of lay down on their side in her hand. The boys do not, they stand up straight.
She grew up on a ranch out here and her grandmother taught her this. I am VERY anxious to see if she is correct. I asked other employees at the store and they said she is usually right on. So, time will tell.
She asked me not to tell all the customers she can do this because she does get busy and does not have time to do Every chick. I am in the store often buying horse and rabbit feed so we have become friends.
If she is correct I will be sure and post about this!
