Discovered today one of my year-old Black Sex Links has no/zero feathers on under belly between legs or under vent. Just bald as billiard ball. The four BSL's look alike and she could be the one that sat on nest all day yesterday but I thought BSL's didn't normally go broody. She, and the other three BSL are top of pecking order so no one pecked her bald. No rooster either. Could this be the start of molting or a broody issue? Regarding molting - from what I've read they molt anywhere from once to as many as 3 times their first year???? My original 13 have never molted. Nine just made a year and four are 9 months old - all different breeds. Any ideas? Why a bald belly and why haven't they ever molted?
