Its like she stopped feathering after about one week or so. She is over a month old and has only limited wing feathers. She is getting taller as her legs have grown fairly long but even her body isnt that large for her age. Here is a pic of her in comparison to another chick that is 3 weeks younger than she is at a month old. The center chick has more wing feather development at one week than she (on the right). What do you think is going on? Any ideas?
