It is definitely going to be a ton of work! I think you should talk to this breeder. Sometimes, your girls all come in together and you have to choose do you breed them now knowing you might have all three take and have three litters or do you wait what is usually 6 to 10 months to get another shot? If the girls just stacked up this time, I would not have a problem as long as the breeder can handle properly raising all the litters at once. If this is the norm, multiple litters all the time, it would turn me off.
From a short look, all the breedings look good for clearences, with the exception of Chelsea. She is missing an eye clearance on Orthopedic Foundation for Animals
. She probably has a clearance that has not been sent in. I would ask the breeder to see it. If she can provide the CERF report, then I would say all the litters are good for clearances in the parent generation.
Personally, I would ask her about the intent behind her breeding program. It is a slight concern to me that all these breeding use what looks to be her own dogs. I may come from a different place here because I would be buying for my own future breeding program. Why where these boys picked for these girls? I feel the best boy to complement your girls is very rarely if ever the boy in your own back yard. There are a lot of nice boys in Texas, why not look to see what would be the best cross to improve your girl regardless of the location? Is she planning on keeping puppies from all the litters? She may have some very good answers to these questions, so if it where me, I would ask.
Good luck in your search. It looks like you are off to a good start!
