Hi Pinky, Welcome to Parrot Chatter.
Thank you very much for helping this little one in need.
Your little one was 3 weeks when found, The bird weans between 5-6 weeks old and the peeping you hear will soon enough fade away as the bird matures.
They are called Squeekers at this age.
If your little one is eating seed and drinking often then its time for "tuff love" and begin the weaning.
Something to take note, Pigeons suck when drinking as we humans do when using a straw, so the water should be 2 inches deep or deeper.
Are you thinking of keeping this little one as a companion bird or do you intend on release? Also, we definitely concerned about psitticosis, which I know runs rampant among pigeons
Psitticosis occurs wilthin all the wild bird familys, If possible could you take a blood culutre and send it in for lab work, you snip a talon nail to get a little blood and drop of at a vets office to check for this disease.
Blood stop will be needed and or table flour will work for stopping the bleeding.
30 days is okay for seclussion however I would wait for 45 days and run a blood sample for lab work before allowing this little one near your other birds.
Pigeons mature at 6 months old, and or are capable of breeding at six months old, all feathers should be in by this time. In the meantime, we've been trying to interact with him some more, but he doesn't seem to want to be with us.
This will be up to you, this bird can be released back into the wild if human touch is limited, if you wish to keep this bird as a companion, more time with the bird will be needed, holding and having a small amount of seed in your hand when having the bird with you will help, when I hand tame it is done right after feedings, I hold the bird and comfort with calm words and alot of kisses and strokes, I do this for close to an hour after each feedings.
Wormers maybe needed, May not be needed, here's a good site to learn more about wormers and determining if there needed,
Foy's Pigeon Supplies - Since 1892!
Do you have a scale that measures in grams?, you can check to see the weight gain, weight gain is important and can give you an idea if wormers are needed.
If you do intend on keeping this little bird then by all means, take the precautions I have mentioned above, Lab work and begin checking the weight.
Wormers should only be used if needed.
If you are intending on release, then limit human contact, hang on to the bird until at least 7 months old and depending on the weather where your at, find a feral flock of Pigeons and release there, the bird will join up with the Ferals and learn all there is to survival from them.
Thank you kindly for helping the little bird of peace, if trained properly, YES, they are very LOYAL companions.
Please let us know what you are going to do and remember we here at Parrot Chatter are here to help you or find someone who can.
