I have five laying hens and one rooster. I believe they are red sex links. My hens seem to be getting skinnier. I have them on a layer mash from a feed supply store. My rooster seems ok but his poo is runny/foamy but not bad. They eat well, free range. There is no other problems. Just seem to be gettting skinny. My hens' poo is normal. My hens started laying about 3 weeks ago and it took me about two weeks to get their layer feed. Could that be the problem? I've seen no worms in poo but I read somewhere that you don't always see worms in their poo even though they have them. Since the layer feed their eggs are much bigger, but they always layed good hard shelled eggs. I just don't know why they are getting skinnier. Any ideas? Should I add something to their diet? I'm worried this could be the beginning of a bigger problem.
