Okay, thanks for the extra information. That really helps. First, the easy part of your question, about the lighting. Full spectrum lighting refers to a light fixture that replaces the portions of light that our birds need from the sun, but do not get when they live inside. Just placing a bird near a window does not help. That's because the portion of the light spectrum that our birds need is filtered out by all modern windows because it's also the part that fades our drapes, carpet and furniture. Proper lighting is needed to help them absorb many of the necessary vitamins and minerals from their food. Even on the best possible diet, a bird may be lacking in nutrition if they don't have proper lighting. This is especially true of calcium, with our Greys. Maintaining proper calcium levels can be hard to do with Greys, especially without the proper lighting to help them out. If those levels get off, hypocalcemic seizures can be the result. An extreme seizure, (not something you want to witness), can include thrashing around, or losing consciousness. A mild seizure can appear as a momentary "zoned out" episode, then the bird is lethargic for awhile, as you describe. For this reason, if no other, it's a good idea for our Greys to have at least, annual checkups to monitor their calcium levels. As for the proper light, you want the bulb to provide 2.4% UVB and 12% UVA. This is neither a recommendation nor an endorsement but it is a link to one such company with further explanation of the lighting requirements.

She won't need a male bird to lay but she will need excellent calcium reserves to make firm egg shells and to hopefully remove the risk of becoming egg bound. Having his calcium levels checked was going to be my first recommendation and I do still think it's important but after you told me about the spray, that's adds another list of possibilities. I don't know if you have ever used that product before on any of your birds or had the opportunity to see any reaction to it but botXXXXX XXXXXne, it is never a good idea to spray anything at all like that on them. Pet store employees, and of course the manufacturers, will often tell you they have the cure to almost anything at all on their shelves when in fact most of it is worthless junk, the rest can be very dangerous. They either don't know, or don't care. The fact is, whatever we put on our birds feathers, ends up in their system. They breath in the mist as it's being sprayed and they ingest it as soon as they preen. A bird's bath, or mist, or shower, (however they prefer to bathe) should never be anything but plain water, or at the most, it can have some 100% pure aloe juice, straight from the plant, mixed in for skin and feather condition. I would suggest you offer him a bath asap and hope he will bathe most of it off. You say he seems to have come out of it and that's great. However, that doesn't help us get to the bottom of the original problem. It could still be either one of those, or something else entirely. I would urge you to get an appointment set up asap with your Avian vet for a check up and a test of calcium levels. In the meantime, keep a very close eye on him for any other symptoms of illness. That might be sitting with feathers fluffed, a change in the appearance of his droppings that lasts more than 24 hours and you can't account for it by diet, a change in overall behavior and/or vocalizations, sitting on the cage floor instead of perches and sleeping an inordinate amount of time. If you see even one of these symptoms, don't wait for more. Get him in right away. I'm going to give you a couple links below where you can read some more about the calcium issues. However, in the one, ignore the part about the spinach. It's relatively recent but it has been found that even though spinach can be good for birds, it also contains oxylates which can interfere with their calcium absorption. Better to stick to the other leafy greens instead. I hope this information helps you out but if you have any more questions, just let me know. Patricia
