My father has asked me to get on the forum and ask .... if anyone has heard of "soft head" or "sore head" in terms relating to chickens? Someone told him if his chickens ate too many watermelons ... they would get soft head or sore head. My father has never heard of this ... and we too have not. A friend of his has a watermelon patch and gave my father several watermelon for his chickens ..... he wants to check on this before he feeds them them a large amount of watermelons.
