I have 3 pullets aged 15 weeks who used to eat their feed like crazy. Lately, for the last 2 weeks, they are taking days to eat the same food and still don't eat it all. I let them roam in the backyard all day long and they are quite fond of the side of my house where I'm sure there are lots of bugs! They go there everyday and my thought is how many bugs could there be over there?? My lawn is just average backyard lawn, and frankly is drying out in spots. Are they getting enough with foraging that they don't want the feed? Don't they need the extra protein that the feed provides in order to be good egg layers and grow properly? How can I get them to eat their food again?!
