POULTRY From page 39 Pecking and feather pulling clearly induce pain from Day 13, and by Day 18 weaker chicks can be pulled down and trodden. When chicks are with their mothers they will copy her dusting activities, starting as young as Day 3. Preening of wing and breast feathers may start at Day 2, but no preen gland is used until Day 14. The preening spells may last up to four minutes. Chickens keep their feathers waterproof by preening. They get oil from a gland located at the base of their tail feathers. This gland is called the uropygial gland, or preen gland. The preen gland secretes an oily/waxy substance which the chicken spreads over its feathers with its beak. If you watch your chickens preening, you will see them periodically rub their beak on an area by the base of their tail to get more oil from their preen gland. Chicks will start pecking at toes by Day 10. If conditions are hot, dry and too bright, they'll pick at wing and tail feathers until they bleed, as well as pecking at pasted up vents. Chicks will peck at any bright object in the litter, which may include nails and staples that can cause death if swallowed, so constant and careful checking of the litter or the area where they spend their day is most important. Litter scratching is a very stereotypical action from Day 2. It is best described as a scratch with the right leg, then two with the left, then one with the right and so on, while the litter is flicked over with the beak. The whole sequence takes about 15 seconds and occurs in the best-lit areas first. If the environment is too cold, litter may be eaten and the gizzard impacted. A study of chicks up to ten weeks old shows many 40 www.sasmallholder.co.za behavioural activities: K Resting is very important just after hatching, declines till three and a half weeks, rises to eight weeks, then declines again. K Females rest more than males. K Leg stretching increases (especially in males) to a peak at four to seven weeks old and then declines. K Scratching increases in the first week, declines to almost nothing at seven weeks and then reappears at nine weeks old. K Preening increases with feather growth while running about decreases with age. K Frolicking increases up to week four and then declines as sparring starts and reaches a peak at week five. K Fighting encounters replace sparring by week seven and this pecking reaches a peak at eight weeks, by which time a clear pecking order is established. Chicks dehydrate quickly at the high temperatures of rearing, so they must find water quickly after hatching and learn to drink. Drinking often starts with the chick pecking at a bubble, and some water movement helps to start them drinking. A good idea is to lay paper on the floor and place the feed and water on that. The chicks will discover both by pecking. Remove the paper after a week as it will be soiled and by then they should all have learned. Be guided by the smallest chicks as they'll be slowest to learn.
