Well I applied it now then, I really didn't keep track of how many days I did it, sorry! She had been bald for 6 months. Then she molted 2 weeks ago and started to grow new feathers and the head feathers grew in. I opened the chicken coop door and was so surprised! So I don't now really much about it but I think it takes Time. Hope she gets her feathers back! (when you got her where feathers missing? how long have they been missing??)
