Thank you for your help! Lol I had someone who knows a little more about rabbits come over and check it out, turns out the light gray one is the female...and is definitely pregnant lol. I'm pretty sure that they are at least Flemish crosses.... The steel colored male has to weigh at least 10 lbs!
*Edited to add-
The female does have a dewlap / double chin, and yes they are in separate hutches now! I was also informed that since they were housed together for an extended period of time at their previous home that the female may be pregnant with multiple litters. So we will also deal with that when the time comes. Wish me luck lol!
