Your bunnies are so cute and I can tell you love them.

However I am distressed to see you have a new? 4 weeks old. Yes, this is the age when they are the cutest but they should not be taken from their mom until they are 8 to 10 weeks old.... Yes they are eating greens but they haven't had a chance to completely learn how to BE a bunny from their mom at this age.
Most females who are removed to early from their mothers often kill their first batch or two of babies because they don't know what they are and how to take care of them. I am involved in rabbit rescue and we see this frequently.

I would hope that you are not intentionally breeding your bunnies and adding to the homeless rabbit population. We have found that rabbits are impulsively purchased this time of year and no thought is given to the care and needs of the rabbit...they are just cute so people want them. They don't realize that bunnies are physically fragile, the amount of work involved, that buns need to eat something other than pellets, and most importantly, that rabbits are NOT like kittens and puppies....that you have to EARN a rabbit's trust and affection. People also do not understand the eye sight factor or why a bunny might freak out and box, charge or bite when something comes at them from the low vision spot in front of their face..... I could go on and on.

What is really sad is that it is only the end of March and already our sanctuary has already seen an increase in people wanting to surrender their bunnies or who have found abandoned ones. What I refer to as the "Easter Dump" hasn't even happened yet...May, June and the first half of July are terrible for us. Last August we were caring for 92-94 bunnies, when our usual population is between 42-50...... I hate to think that the early surrenders we are seeing are a portent of things to come later this spring. PLEASE reconsider if you are purposefully breeding your bunnies, and if you aren't, congratulations! You are doing the right thing.
