We got 9 chicks about 6 weeks ago and they are all fully feathered. I have been reading and it says to start chicks on pullet grower about this time. I have been feeding them IFA chick starter and just switched over to Nutrina nature smart chick starter grower and their food consumption has gone down to where they are almost eating nothing. They have been scratching the floor looking for their old food. The starter was like a powder almost, the new food is a crumble. Any suggestions on what to do?
