Initial Care:
General bird information:
- On arrival any young bird should be weighed, warmed, and given
supplementary fluids by an appropriate route to counteract dehydration.
- Cold, weak chicks may benefit greatly from a short period, for example 30 minutes, left
in a dark cardboard box at 30-35°C.(P19.1.w4)
- The age should be determined if possible.
- See: Hand-rearing
of Orphaned Wildlife for further general information.
General Care (including warmth and hygiene):
General precocial bird information:
- Young chicks have a poor ability to maintain body temperature and are prone to
hypothermia, hyperthermia and burns.
- Keep out of draughts but ensure ventilation is adequate. (V.w5)
- A thermometer should be used, within the brooder box, to indicate the temperature at
which the chicks are being maintained.
- Provide heat to a maximum of 95°F initially directly under a heat lamp, with a
temperature range such that the chicks can chose the position at which the temperature is
comfortable. Ensure the minimum temperature is not low enough to allow the chicks to get
chilled.
- Reduce the temperature gradually as the chicks grow so that by the time they are fully
fledged no heat is required.
- (B118.5.w5,
V.w5)
Specific information:
- Very young chicks of these species require heating provided by e.g. an infrared
lamp. (B233.7.w7)
Food:
A variety of diets have been suggested for hand-rearing gulls including:
- Mash of raw fish, brown bread, cod liver oil and milk initially.(B118.5.w5,
B186.8.w8)
- Strips of fish such as herring, eel, trout, minnows, whitebait.(B118.18.w18,
B203)
- Depending on size/age of the bird feed slivers of whitebait, whole white bait and mashed
fishy cat food. (D24)
- Fish, dog food or day-old chicks.(B151)
- Pilchards in tomato sauce, mixed with bread crumbs has been used
successfully. (B199)
- Fish, preferably whole fish of an appropriate size for the chick to
swallow, otherwise sliced into appropriate-sized pieces, and supplemented with thiamine.(B233.7.w7)
- Offer food quite moist. (B199,
B203)
- Supplement fish with vitamin/mineral mix.(B203)
Feeding Frequency:
Suggested feeding protocols include:
- Four to six times daily depending on age.(D24)
- Hand feed twice daily.(B233.7.w7)
Feeding Technique:
- Hand feed very young chicks, offering food from above the bird.(B118.5.w5,
B118.18.w18,
B186.8.w8,
B203)
- Chicks should eat independently and not require hand feeding, from an early age.(D24,
B199)
- Stimulation with an artificial "bill", with a red spot painted
on it, presented for the chick to peck at, could be useful for reluctant feeders.(B199)
- Force-feeding may be required initially although this is unlikely with
gulls. (B233.7.w7)
Quantities:
General bird information:
- Most species of bird eat 10-20% of their body weight per 24 hours. (B150.w2)
- Do not necessarily feed until begging stops: chicks may beg well past the point at which
their upper digestive tract is full.(B150.w2)
- Carnivorous birds (raptors, fisheaters, shore birds) may take up to 50ml/kg body weight
per feed.(J34.9.w1)
Toileting:
Weighing:
General bird information:
- Regular weighing provides a good indication of growth, however a balance
must be chosen between the frequency of weighing for accurate monitoring of progress and
the stress which may be caused by repeated handling.
- Individuals in a brood or being reared in a group must be individually
identifiable in order to allow the progress of each chick to be monitored.
- Temporary identification may be made possible using small colour marks
applied to the feathers. An appropriate non-toxic material such as coloured correction
fluid (e.g. Tippex) or nail varnish may be used for this purpose.
- Alternatively, for larger chicks, lightweight leg rings made of flat
plastic may be used. These are available in a wide variety of colours. Rings must be of an
appropriate size and changed as the bird grows.
- (B150.w2,
V.w5,
V.w26)
Weaning:
- By 3 weeks old (should be fully fledged), chicks should be taking chopped herring,
mackerel, chopped chick, with vitamin/mineral supplementation.(D24)

of Casualty Gulls & Terns
Release:
- General bird information:
- Move to an aviary for at least two weeks prior to release, to allow exercise,
flying/swimming as appropriate, and exposure to the weather.
