He is she!

Apologies for my 1st post being a question, I'm hoping for a bit of advice and reassurance.I have Milo the grey and Ed the Amazon. Milo is somewhere around 15 or 16 yrs old(I've had him/her since a baby but my memory for dates is awful! about a month ago he became really spiteful to Ed who was here before Milo and they've lived together fairly harmoniously till now. The reason for Milo's behaviour change became apparent when I found him/her on the bottom of their enclosure with an egg!! She(!) Has gone on to lay 2more,the last being about 2wks ago..just for info, they have a purpose built enclosure which is huge with a walkway to outside enclosure,their door is open a lot of the time so they are free to have a wander into the conservatory,hall etc.they both sit with us in the evening. They have a lamp in their "cage", they have calcium drops in their water, I used to do 3times a week but now doing every day because of the eggs.I have "shortened " Milos day by putting her to bed earlier,she is still preferring to sit on the bottom of the cage where she laid the eggs(which I removed) she is otherwise normal,is eating well,talking,behaves normally when I bring her out,but doesn't leave the floor voluntarily except to eat/drink. fortunately she has become less aggressive to poor Ed.My question is how long can I expect this to continue?,am I doing the right things?..Sorry for the essay!!

Seems you are observing classic nesting behavior from Milo. Do you know Ed's sex? Unsure if amazons and greys are capable of producing a hybrid.

Do Ed and Milo engage in courtship behavior? Something is stimulating Milo, and excessive egg production is unhealthy. Most species can become egg-bound though it is less common with larger parrots.

Greys need additional calcium, though I'd add to water only by advice of certified avian vet. Difficult to know how long this behavior may last. Depending on your location, might be breeding season.

Excellent advice from my good friend!

Your location is very important as both are effected by seasonal changes in the amount of sunlight (day vs night) and other less obvious variation including changes in diet. At this point, you are either leaving or entering mating season.

In the Northern Hemisphere, this for whatever reason has been a long and intense season and from what we are hearing, the Southern Hemisphere 'appears' to be continuing the trend.

- Time to take your Amazon to your Avian Medical Professional (CAV) and have s/he DNA tested! And, IMHO, it's time you should be having them both in yearly for a full physical that includes a full spectrum blood testing, including checking the chemistry that defines the heart. If you're Parrots' are flighted, it is important to assure that your CAV is aware of that fact as muscle are heavier than fat.

There is good reason to believe that your (New World (America)) Amazon and your (Africa) Grey are not likely to breed. But, even though unlikely, it is possible. IMHO, such a Hybrid would likely have sever physical issues and every effort to avoid such an occurrence should be undertaken.

FYI: Avoid removing the egg(s)! At most, a short removal to freeze the egg (killing it) and than back in the enclosure... This will limit her laying more eggs.

Enzo has laid 4 eggs three 3 times now. The last time I left her with the eggs for far too long, in future I will give it a few weeks before removing them. It is that season now and early nights are a must, no warm mushy foods, petting etc etc.

Are other parrots the same as greys, they seem very hormonal.
