If they are eating, drinking and scratching about they generally are okay. Reproductive problems won't necessarily make them sick so if there's damage to the ovary the hen would stop laying.Thanks I’ll review the feed etc to make sure. I can’t see any obvious signs of illness. Anything I should look out for?
How old is this hen? Some hens have a significant drop in production after 2-3 seasons.
I recommend a feed with 18-20% protein to optimize laying.
