How are squirrels kept and bred? Frequently asked questions answered
1. Keeping environment Squirrels are very lively, especially fond of climbing trees, and their activity space is fairly three-dimensional, so a wide and tall cage should be chosen as far as possible. Since squirrels are used to building nests in trees, the nest box should be installed high up in the cage. A nest box intended for small birds with the entrance at a high position can be used instead.

What are the environmental requirements for goose breeding and incubation?
A small-scale goose farm can let the geese hatch naturally, or use a female goose as a surrogate incubator. A large-scale goose farm needs to use artificial incubation, and the incubation period is 31 days. Select fresh breeding eggs of suitable size, normal egg shape, color meeting the breed requirements, and clean surface, fumigate with formaldehyde

Environmental Requirements and Management Techniques for Hatching in Rice Field Eel Aquaculture
The hatching rate of fertilized rice field eel eggs is affected by various environmental factors, among which the main ones are water temperature, dissolved oxygen and harmful organisms. (1) Water temperature The embryonic development of rice field eel is extremely closely related to water temperature. This is mainly shown in three aspects: first, embryonic development must be carried out at a suitable water temperature; too high or too low will cause a decline in hatching rate or embryonic deformity. Studies show that the suitable water temperature for embryonic development of rice field eel is 21-28°C, and the optimal water temperature is 24-26°C; second, within the suitable water temperature range, too large or too rapid a water temperature difference can also cause embryonic deformity or death, and it is usually required that the temperature change within a short time should not exceed 3°C, and preferably not exceed 1°C; third, the length of embryonic development time of rice field eel is directly affected by water temperature. At a water temperature of about 30°C (28-36°C), embryonic development takes 5-7 days, and at a water temperature of about 25°C, embryonic development takes 9-11 days.

How to manage the chicken coop environment in autumn and winter
Temperature The temperature inside the coop should preferably be kept at 18-23°C, and should not be lower than 15°C at minimum. If windy weather occurs, the tarpaulin should be rolled up (roll up half or all of it according to changes in the outside temperature) to prevent the wind from causing the temperature inside the coop to drop suddenly. Every day, adjust the size of the air inlet according to the weather conditions and
