Hello, We have four chickens, two red stars that are 18 months that usually get some cracked corn every day about a handful. And our little chicks about six weeks maybe eight. Anyways my question is, what type of treats should we give them, how much of the treat? I've heard people say watermelon. but how much a slice? Do we take out the seeds? What if its to much water?(if there is such a thing.) When can we give the chicks treats? Is it okay to give them some now? Please let me know. Thanks!
