Before you begin to harvest the butterfly weed pods, sterilize your cutting tools. Dip the blades into a full-strength household cleanser, such as Lysol or Pine-Sol. Repeat between cuts to prevent the spread of diseases.
Watch for germination in two to three weeks. Turn off the propagation mat one week after the seeds sprout. Move the pots into a cold frame outdoors or against a south-facing wall with noonday shade.
Butterfly weed and milkweed seed pods may be harvested and planted to support Monarch butterfly caterpillars.

But, I have had rabbits eat young or tender foliage of Butterfly Weed. They mainly seem to be at risk at the seedling stage, or when first emerging in Spring. But rabbits will eat Butterfly Weed.

5 – Keep the soil moist. Water only in the morning (if possible).
If you are concerned, the safest solution is to top-dress the plant with compost. Applying a 1-2″ thick ring of compost around the plant will take care of any nutrient deficiencies the plant may be experiencing. If that fails to address the yellow leaves, consider
