These are the first chickens I have ever had and I'm constantly afraid I'm doing something wrong.. I have 6 EES and 2 Silkies all around 11 weeks of age. They have had free access to organic grower/starter food since I got them around 4 weeks old but I feel like they are skinny. I've started to let them free range for a couple hours each afternoon and plan to leave them or more once the silkies are too big for my cats to eat. Going to get wormer in the next couple days even though I haven't seen any sign of them other than them being skinny. What else should I be doing??
