Any fruits and vegetables not listed above.
Dried corn.
Live Grubs like black fly larvae, meal worms, soldier fly larvae.
Seeds
Nuts, but offer these sparingly as they are very high in fat.
Dried woodland mushrooms (human safe only).
Edible flowers such as marigolds, rose, nasturtium, lavender.
Herbs such as parsley, oregano, thyme, lemon balm, rosemary
Rolled oats, again offer these sparingly as they are high in fat and do not offer a huge amount of nutrition, but porridge is great to give in the winter months late in the afternoon as the hens will stay warm burning the porridge through the night.
It is illegal to feed your chickens dried grubs, meat or kitchen scraps.

Chickens love treats, and we love treating them, just like we do for any other pet, however, be careful with treating as not all foods are suitable and over treating can be harmful.

Chickens need different types of feed at different stages of their lives. From day old to about 6 weeks they can have a chick crumb.

From 6weeks to about 14-20 weeks (depending on breed) they can have Grower or rearer pellets.

From 14-20 weeks and up they should be on a good quality layer pellet or layer mash. Their pellet feed should make up 80-90% of their diet. You can then supplement the rest with lovely treats, but treats should be given sparingly as if you over treat your hens will want this and not eat their pellet feed, they need the pellet feed as this has been nutritionally designed to give them most of the vitamins, minerals, protein etc… they need. You should not feed corn, wheat or barley as their main feed.

If caught early enough an antibiotic can usually treat the infection with great success, the most common treatment is Tylan, you will need to contact a vet to get a prescription for this antibiotic.

The most common symptoms are swollen eyelids and sinuses, rattly breathing, sneezing, wheezing and coughing, you can usually hear gasping wheezes at night this is when the birds’ systems are relaxed and the respiratory issues are easier to hear.

You might also see bubbly clear fluid/foamy discharge from the eyes (Mycoplasma Gallisepticum).

Thick yellow pus in the eye sockets and sinuses (Mycoplasma Synoviae).

Swollen joints and thin shells at the round end of the eggs (Mycoplasma Synoviae).

Mycoplasma is a bacteria not a virus mainly attacking the respiratory system but can also affect the kidneys, Infected birds become carriers, remaining infectious for life, although some birds may become immune.

Do not over treat, chickens will free feed much like cows, they graze on their feed throughout the day, ensure your chicken’s feeder always has feed in but keep this feed as per the recommended pellet feed for the age of hen you have. You can supplement this with treats but treats should only make up 10-20% maxim of their diet. Do not feed your hens purely on scraps and corn as this will cause them to hold onto too much fat.
