An issue that keeps cropping up…
One of the more regular calls I receive at Hen Central relates to issues with the crop.
For those among you that are more novice hen keepers the crop is the hen’s shopping basket. It sits on the front of the hen’s chest and is more prominent as it fills. Through the day she will collect tasty morsels of food and her crop can grow to the size of a small orange.
The crop will empty overnight as the food passes down into the stomach.
You should know what feels normal to ensure that you spot anything abnormal quickly. Check your hens on a regular basis and compare one to another – you will quickly learn to spot any problems.
If your hen has been eating long stringy grass or foreign objects like string or plastic, the crop can become impacted. The material will cause a physical obstruction and will prevent food passing into the stomach. If the blockage is not too large your hen may benefit from a dose of warm liquid paraffin or olive oil (5ml/1 teaspoon). Gently massage and allow access to tepid water, but no food should be offered as this will only add to the impaction.
If the blockage does not pass through overnight it is essential that you seek veterinary help as a small surgical procedure may be needed to remove the material through the crop wall.
Occasionally hens can develop sour crop. This is due to an imbalance in the normal crop flora (bacteria) and a fungal overgrowth. Often this starts when your hen eats damp or mouldy feed, but it can also follow after a treatment of antibiotics.
The crop will appear full but will have a squishy fluid filled feel to it. Often a foul smell will be detected if you open the beak and sniff. In severe cases just lifting the hen up and putting pressure on the crop may cause fluid to come out of her beak. She may flick her head and will be dull and off food. In mild cases hens can be treated by withdrawing food and water and dosing with 3ml of neat brandy which we have found kills off the fungus. A probiotic 48 hours after treatment ends will help replace the natural crop bacteria. Small amounts of food (teaspoon) and warm water (teaspoon) may be re-introduced after 24 hours. In severe cases veterinary intervention may be required. Draining/flushing and treatment with antifungals may be necessary. Crop emptying should only be attempted by experienced hen keepers or professionals.
The final crop problem is a pendulous crop. This is more usual in older hens and is a result of weakness in the crop wall and poor muscle tone. The crop will hang lower and grow bigger than normal and food will take longer to pass through. Although it looks odd your hen will cope with this condition and live a normal life. Ensure grit is added to the diet and feed smaller meals if possible. For the more fashion conscious hen a crop bra can be used (yes really!) which will offer some support.
