I have about 4-5 pullets walking around this morning holding their wings out from their bodies. When I walk to them to pick them up, they straighten up and scamper off not making it easy to get a hold of them. There are 3 that I can usually pick up with no problem. They are 19 weeks old and no one is laying just yet. I still have them on starter feed since they haven't started laying yet, and I can only get starter or layer here. I did have to go to TSC to get feed the last time because we usually go to Southern states and they were closed. This new feed is medicated (my only option), and they have been on it for about a week. The Golden comets are the only ones doing this! Is this something that I need to be concerned with?
