Peach faced lovebirds

Question
Hello and how are you? I'm good. I have three peach faced lovebirds a normal green male and two lutino females the male is 1 1/2 and the hesn are 6 1/2 months old they all live together my male has picked a female and they haev become very close... he even feeds her now. I bought the hens for company and because I'd like to breed lovebirds on a very small scale. I noticed he is chasing the spare female off when she comes close to her sister so I think she will need to be removed when they start to breed for her safety. I was reading and the hen is suppsoed to be 10 months old before she is bred correct? I don't want to hurt them they are such beautiful birds and are my pets first and foremost. I am eamiling to ask if there is a different diet I should be giving them now to prepair them for breeding? Right now the trio get Zupreem natural cocktiel/small hookbill pellets and hartz bonanza cockatiel seeds mixed together the mix is mostly pellets...they also gets spray millet a few times a week one or two sprays at a time....is this too much I am not overly sure. They wont eat veggies I've tryed all different types finely and coursely chopped but they barely touch them and they just go bad in the cage and need to be tossed out. Also I have no idea if you've ever bred lovebirds but was wondering what to expect when I do give them there nesting box in a few months? would they nest right away? Thanks a bunch please answer what you can I understand if you havent had experiance with breeding and can't answer those questions but I would really like to know what they should be eatting.

Answer
Hello Lee and thank you for your post.
Yes, the spare female will have to be separated from the other two.  As for the breeding, I like to wait until they are at least a year and a half old before they breed for the first time.  This will give their body a chance to fully mature.  Putting a nesting box into the cage will stimulate them to breed most of the time (but not always).  At first they will shy away from it, but then they will start going into it.
Continue to offer fresh fruits and vegetables.  Just offer smaller quantities if you're having to throw too much away.  Seeds are fine as a treat or a reward...but that's it.  Your birds should be on a pelleted diet.  The millet spray is fine the way they are getting it, but again, I only use that as a treat or reward when I am training my birds.
You can also try offering them some fully cooked boiled chicken and beef (unseasoned).  Birds love this, and all of the lovebirds that I've ever had went crazy for it.  Once or twice a week for this is good.
I hope that I was able to answer your questions.  Please feel free to come back and ask any more questions that you might have.

Good luck and God Bless.
