My bunny is 30 days pregnant and not building a nest she looks chubby to me and I thought she was pregnant! Now I am not so sure. This is her first litter. can someone give me advice please it would really be appreciated
Give her nestbox, nesting material, and peace - don't stress her.
And keep checking, it can go pretty fast when the time comes. My does start nesting in earnest just before they deliver, but if something doesn't go right, like first timers messing up the right sequence, or having kits outside the nestbox, it's good to interfer asap.
You can prepare, by giving her more calcium rich food or even a (fruit flavoured) Tums, and you can gather a pile of fur or prepare a substitute like dryer lint or cotton wool if she doesn't pull enough or too much gets wet and soiled.
One of my does usually kindles at day 32, the other at day 35, can't tell about the others.
