Excellent clutch, Mom should 'bounce' back just fine if she is, as you describe, a large lady to begin a breeding programme.
Offer a small meal prior to her post-lay slough & she will, most likely, appreciate the extra energy that it will provide.
B.T.W. I, also, had a large 23 egg clutch from a 1st time Breeder in 2007. A Snow Motley/Stripe, who then double clutched for me too!
