The topic of feather pecking/eating is one that comes up fairly often, so this week I would like to hear you all's thoughts on this dilemma and what step(s) you've taken to help stop/prevent it. Specifically:
- What causes the flock to start pecking/eating each others' feathers?
- What level of pecking is normal is what is not? (For new chicken keepers)
- How can you prevent/stop feather pecking/eating?
As a pre-cursor to the content below, I do not have any experience in dealing with feather pecking, feather eating or cannibalism. I live on the equator, so we have no winters or changes in daylight hours. As consequence, my flock ranges in the garden from dawn till dusk every day, thus having no break in routine. I am however, interested in chicken behaviour and I've done a little reading on the subject. It is only intended as background information. I have included the sources consulted as links.
- What causes the flock to start pecking/eating each others' feathers?
Temperature changes
Overcrowding
Temperament (individual / breed)
Sudden changes in feed composition
Temporary unavailability of water / food (e.g. frozen drinking water)
Unevenness of the flock in terms of size (weight) / colour
Parasite infestation (either of coop or birds)
Sub-optimal nutritional balance (e.g. mineral, salt or amino acid levels deficiency)
Use of vegetable protein in feeds
Inadequate foraging incentives - e.g. the use of pellets / coarsely ground feed reduces time spent foraging
Significant variations from a flock’s routine - limited ranging opportunities due to weather
Triggers to feather pecking are most likely to be the result of a combination of potential stressors.
- What level of pecking is normal is what is not? (For new chicken keepers)
Gentle pecking – part of the establishment and maintenance of pecking order and an essential part of social behaviour. Usually concentrated on the head / face area. Often observed as part of preening behaviour
Aggressive pecking – abnormal and persistent pecking and removal of feathers on the head (commonly seen in younger birds) or most commonly seen on the base of the tail, preen gland area, tail feathers, back or vent / below the vent pecking in adults
- How can you prevent/stop feather pecking/eating?
Ensuring sufficient coop and run space
Having sufficient feeding / drinking stations
Maximising the time the flock spends foraging
Provisions for dust bathing or use a friable litter than will facilitate it
Feeding high fibre, low energy diets (read the ingredients and proportions on the feed you buy)
Installing objects in the run / coop to "entertain" the flock (distractions)
Providing an object(s) that can be pecked at - e.g. a bale of straw
Add perches to the housing
