She was paired with another tiel in the same cage. who supposedly is a pied cock yet to confirm the gender. Anyway, he is way too young for breeding he is 7 months.
Do you want to breed her? The male is old enough to breed, but he is still a baby...
The young cock likes to sit on the eggs but after I put in the nest box the hen won’t let him go near it. up to the point that she is attacking him and I had to separate him to another cage. after the 4th egg was laid I candled all the eggs and they all were blanks. They seem not to be compatible at all.
Many hens can be like this. It certainly doesn't sound like a true pair. Generally speaking, they are supposed to take turns sitting on the eggs... i.e. mom sits on them during the, dad sits on them at night.
You *must* candle the eggs ~1 week *AFTER* the hen has been sitting on the eggs to know if they are fertile or not. (this can be done as early as 5 days, but easier to tell at 7 days)
I got another mature 3-year-old cock. Putting the new pair next to each other didn't raise any red flags. my question is should I wait until the hen sits on the eggs for the 21 days and remove the eggs or remove the eggs now and put the new pair in the same cage?
Is the cage large enough for 4 cockatiels? Adding more birds could cause stress and potentially aggression between them.
This is her first clutch ever. How do I make her stop laying eggs? is it by reducing sunlight hours?
You need to first figure out what's triggering the behavior. Having a nestbox is not helping.... even having the male around could be triggering it.
The other fear is since she is the only one sitting on the eggs she is getting very little time to eat. Just by looking at her she has lost a lot of weight.
Can you weigh her in grams? Losing weight is not good for her!
Should I introduce the second cock into the cage to maybe help her sit on the eggs?
Is the second male cockatiel and her bonded? If the answer is no, then the answer is no. Again, you could be causing more stress.
