My hens have been in some sort of molt for the last two months and now are not laying more than two eggs per day and on some days there is none. The combs are bright and red and hens love to free range whenever they are let out. I cannot determine why my hens, that were purchased with another eighteen hens and distributed to two other friends, are the exception and not the rule compared to the other hens my friends have. One of the other flock owners lives three homes away and he's getting four to five eggs per day. The other flock owner is getting on average ten eggs out of her twelve hens. The hens are eighteen months old. So what's my problem? Your feedback is appreciated.
