I need to move my rabbits back into their three-seasons rabbitry a little sooner than I had expected. They have been in a semi-heated porch (50 -70 degrees, depending on the weather and sunshine) since November. The nightime outdoor temperatures here vary from about 25 - 35 degrees Fahrenheit at this time of year. Daytimes should mostly be above freezing and the tendency this year seems to be toward an early spring. Our last frost date is around May 24. Will my rabbits need to be acclimatized in order to cope with the temperature change when I put them outdoors? Their cages will be off the ground in a chain-link structure covered with a tarp to protect them from rain. Smaller tarps are used strategically on the walls when the the wind is high. They did great there last summer and fall, but I moved them into the porch to make caring for them easier in winter and to avoid losing kits to the cold. Last fall, the temperatures were every bit as variiable as spring temperatures would be now, but I am concerned about them getting sick. Or am I worrying needlessly?
