Question
Re. unexplained loss of Buff Orpington
My mixed chicken flock, hereto previously healthy, two weeks ago started "picking." Four out of 24 birds show signs of bare bottom spots. I have treated w/ a mixture of Desitin and GoldBond Med. powder, sometimes mixed w/ olive oil. One of the birds is a rooster. They continue w/ good appetite and drinking water.
New flock
New coop, 8' by 8', lino floor, good ventilaton, hanging water and food inside during winter, some food/water hanging during summer
Sliding door and ramp for coop access
Enclosed yard, 12-inch deep w/ clean sand, 25' by 35', fenced and wired perimeter and top.
Yesterday morning I found a dead Buff in a floor-level nest, head hanging over side of box. No exterior damage, no picking evident on this hen.
Constant temp in coop 30F, 4 feet above floor. All roosts well spaced 4' or more above floor.
Two months ago, I started a 'treat' program w/ some cracked corn on ground outside in the mornings; regular feed and water are always in coop only. In summer, water also hanging in fenced yard. For winter, water is set on heating pan (not hanging) in coop.
Possibilities:
Hen was stepped on inadertently by other hen in a low next box?
Disease made her weak to changing temperatures?
Coccidiosis?
