My husband and I went on vacation last week and the in-laws took care of our chickens while we were away. However, to lighten the load slightly I bought a Flock Block so they would only have to worry about changing the water for them. Now that we are back home I have not yet removed the Flock Block from their run because there is still a lot of it to be eaten.....now the chickens are eating on that and not eating their regular feed. They are about 16 weeks old and haven't starting laying yet, will the Flock Block be o.k. to keep in the run, or should I remove it so that they continue to eat their regular feed?? Any feedback would be greatly appreciated!! Thanks!
